GASFLOW comparisons with bureau of mines experiments  

DOE Green Energy (OSTI)

At the request of the Department of Energy and Westinghouse Hanford Company, the Bureau of Mines has investigated the flammability of mixtures of hydrogen, ammonia, nitrous oxide, and air. The tests were performed in a spherical chamber under quiescent and turbulent conditions. This paper describes combustion calculations using the GASFLOW code and compares the calculated pressure ratios with experiments mentioned above. GASFLOW is a finite-volume computer code that solves the transient, three-dimensional, compressible fluid, Navier-Stokes equations with multiple species coupled with finite-rate chemical kinetics. The computational results show good agreement with the experimental data and confirm GASFLOW to be a valuable tool for evaluating the above combustion process.

Before wireless technologies were available, all the sensory connections and user interfaces in nuclear power plants had to be hard-wired. This was a limiting factor in developing a world-class condition-based maintenance (CBM) program. The wire runs were very expensive, and some equipment was in a remote or inaccessible location. With wireless technologies, adding continuous monitoring to equipment is often easy and inexpensive. ...

Insecurity of Wireless Networks  

SciTech Connect

Wireless is a powerful core technology enabling our global digital infrastructure. Wi-Fi networks are susceptible to attacks on Wired Equivalency Privacy, Wi-Fi Protected Access (WPA), and WPA2. These attack signatures can be profiled into a system that defends against such attacks on the basis of their inherent characteristics. Wi-Fi is the standard protocol for wireless networks used extensively in US critical infrastructures. Since the Wired Equivalency Privacy (WEP) security protocol was broken, the Wi-Fi Protected Access (WPA) protocol has been considered the secure alternative compatible with hardware developed for WEP. However, in November 2008, researchers developed an attack on WPA, allowing forgery of Address Resolution Protocol (ARP) packets. Subsequent enhancements have enabled ARP poisoning, cryptosystem denial of service, and man-in-the-middle attacks. Open source systems and methods (OSSM) have long been used to secure networks against such attacks. This article reviews OSSMs and the results of experimental attacks on WPA. These experiments re-created current attacks in a laboratory setting, recording both wired and wireless traffic. The article discusses methods of intrusion detection and prevention in the context of cyber physical protection of critical Internet infrastructure. The basis for this research is a specialized (and undoubtedly incomplete) taxonomy of Wi-Fi attacks and their adaptations to existing countermeasures and protocol revisions. Ultimately, this article aims to provide a clearer picture of how and why wireless protection protocols and encryption must achieve a more scientific basis for detecting and preventing such attacks.

Attacking Automatic Wireless Network Selection  

E-Print Network (OSTI)

Wireless 802.11 networking is becoming so prevalent that many users have become accustomed to having available wireless networks in their workplace, home, and many public places such as airports and coffee shops. Modern client operating systems implement automatic wireless network discovery and known network identification to facilitate wireless networking for the end-user. In order to implement known network discovery, client operating systems remember past wireless networks that have been joined and automatically look for these networks (referred to as Preferred or Trusted Networks) whenever the wireless network adapter is enabled. By examining these implementations in detail, we have discovered previously undisclosed vulnerabilities in the implementation of these algorithms under the two most prevalent client operating systems, Windows XP and MacOS X. With custom base station software, an attacker may cause clients within wireless radio range to associate to the attackers wireless network without user interaction or notification. This will occur even if the user has never connected to a wireless network before or they have an empty Preferred/Trusted Networks List. We describe these vulnerabilities as well as their implementation and impact. 1

Approaches for a quantum memory at telecommunication wavelengths  

Science Conference Proceedings (OSTI)

We report experimental storage and retrieval of weak coherent states of light at telecommunication wavelengths using erbium ions doped into a solid. We use two photon-echo-based quantum storage protocols. The first one is based on controlled reversible inhomogeneous broadening (CRIB). It allows the retrieval of the light on demand by controlling the collective atomic coherence with an external electric field, via the linear Stark effect. We study how atoms in the excited state affect the signal-to-noise ratio of the CRIB memory. Additionally we show how CRIB can be used to modify the temporal width of the retrieved light pulse. The second protocol is based on atomic frequency combs. Using this protocol we verify that the reversible mapping is phase preserving by performing an interference experiment with a local oscillator. These measurements are enabling steps toward solid-state quantum memories at telecommunication wavelengths. We also give an outlook on possible improvements.

Biomonitoring with Wireless Communications  

SciTech Connect

This review is divided into three sections: technologies for monitoring physiological parameters; biosensors for chemical assays and wireless communications technologies including image transmissions. Applications range from monitoring high risk patients for heart, respiratory activity and falls to sensing levels of physical activity in military, rescue, and sports personnel. The range of measurements include, heart rate, pulse wave form, respiratory rate, blood oxygen, tissue pCO2, exhaled carbon dioxide and physical activity. Other feasible measurements will employ miniature chemical laboratories on silicon or plastic chips. The measurements can be extended to clinical chemical assays ranging from common blood assays to protein or specialized protein measurements (e.g., troponin, creatine, and cytokines such as TNF and IL6). Though the feasibility of using wireless technology to communicate vital signs has been demonstrated 32 years ago (1) it has been only recently that practical and portable devices and communications net works have become generally available for inexpensive deployment of comfortable and affordable devices and systems.

Hierarchical Routing over Dynamic Wireless Networks  

E-Print Network (OSTI)

Wireless network topologies change over time and maintaining routes requires frequent updates. Updates are costly in terms of consuming throughput available for data transmission, which is precious in wireless networks. In this paper, we ask whether there exist low-overhead schemes that produce low-stretch routes. This is studied by using the underlying geometric properties of the connectivity graph in wireless networks.

A Measurement Management Technology for Improving Energy Efficiency in Data Centers and Telecommunication Facilities  

SciTech Connect

Data center (DC) electricity use is increasing at an annual rate of over 20% and presents a concern for the Information Technology (IT) industry, governments, and the society. A large fraction of the energy use is consumed by the compressor cooling to maintain the recommended operating conditions for IT equipment. The most common way to improve the DC efficiency is achieved by optimally provisioning the cooling power to match the global heat dissipation in the DC. However, at a more granular level, the large range of heat densities of today's IT equipment makes the task of provisioning cooling power optimized to the level of individual computer room air conditioning (CRAC) units much more challenging. Distributed sensing within a DC enables the development of new strategies to improve energy efficiency, such as hot spot elimination through targeted cooling, matching power consumption at rack level with workload schedule, and minimizing power losses. The scope of Measurement and Management Technologies (MMT) is to develop a software tool and the underlying sensing technology to provide critical decision support and control for DC and telecommunication facilities (TF) operations. A key aspect of MMT technology is integration of modeling tools to understand how changes in one operational parameter affect the overall DC response. It is demonstrated that reduced ordered models for DC can generate, in less than 2 seconds computational time, a three dimensional thermal model in a 50 kft{sup 2} DC. This rapid modeling enables real time visualization of the DC conditions and enables 'what if' scenarios simulations to characterize response to 'disturbances'. One such example is thermal zone modeling that matches the cooling power to the heat generated at a local level by identifying DC zones cooled by a specific CRAC. Turning off a CRAC unit can be simulated to understand how the other CRAC utilization changes and how server temperature responds. Several new sensing technologies were added to the existing MMT platform: (1) air contamination (corrosion) sensors, (2) power monitoring, and (3) a wireless environmental sensing network. All three technologies are built on cost effective sensing solutions that increase the density of sensing points and enable high resolution mapping of DCs. The wireless sensing solution enables Air Conditioning Unit (ACU) control while the corrosion sensor enables air side economization and can quantify the risk of IT equipment failure due to air contamination. Validation data for six test sites demonstrate that leveraging MMT energy efficiency solutions combined with industry best practices results in an average of 20% reduction in cooling energy, without major infrastructure upgrades. As an illustration of the unique MMT capabilities, a data center infrastructure efficiency (DCIE) of 87% (industry best operation) was achieved. The technology is commercialized through IBM System and Technology Lab Services that offers MMT as a solution to improve DC energy efficiency. Estimation indicates that deploying MMT in existing DCs can results in an 8 billion kWh savings and projection indicates that constant adoption of MMT can results in obtainable savings of 44 billion kWh in 2035. Negotiations are under way with business partners to commercialize/license the ACU control technology and the new sensor solutions (corrosion and power sensing) to enable third party vendors and developers to leverage the energy efficiency solutions.

Impact of Distributed Energy Resources on the Reliability of a Critical Telecommunications Facility  

DOE Green Energy (OSTI)

Telecommunications has been identified by the Department of Homeland Security as a critical infrastructure to the United States. Failures in the power systems supporting major telecommunications service nodes are a main contributor to major telecommunications outages, as documented by analyses of Federal Communications Commission (FCC) outage reports by the National Reliability Steering Committee (under auspices of the Alliance for Telecommunications Industry Solutions). There are two major issues that are having increasing impact on the sensitivity of the power distribution to telecommunication facilities: deregulation of the power industry, and changing weather patterns. A logical approach to improve the robustness of telecommunication facilities would be to increase the depth and breadth of technologies available to restore power in the face of power outages. Distributed energy resources such as fuel cells and gas turbines could provide one more onsite electric power source to provide backup power, if batteries and diesel generators fail. But does the diversity in power sources actually increase the reliability of offered power to the office equipment, or does the complexity of installing and managing the extended power system induce more potential faults and higher failure rates? This report analyzes a system involving a telecommunications facility consisting of two switch-bays and a satellite reception system.

Surety of the nation`s critical infrastructures: The challenge restructuring poses to the telecommunications sector  

Science Conference Proceedings (OSTI)

The telecommunications sector plays a pivotal role in the system of increasingly connected and interdependent networks that make up national infrastructure. An assessment of the probable structure and function of the bit-moving industry in the twenty-first century must include issues associated with the surety of telecommunications. The term surety, as used here, means confidence in the acceptable behavior of a system in both intended and unintended circumstances. This paper outlines various engineering approaches to surety in systems, generally, and in the telecommunications infrastructure, specifically. It uses the experience and expectations of the telecommunications system of the US as an example of the global challenges. The paper examines the principal factors underlying the change to more distributed systems in this sector, assesses surety issues associated with these changes, and suggests several possible strategies for mitigation. It also studies the ramifications of what could happen if this sector became a target for those seeking to compromise a nation`s security and economic well being. Experts in this area generally agree that the U. S. telecommunications sector will eventually respond in a way that meets market demands for surety. Questions remain open, however, about confidence in the telecommunications sector and the nation`s infrastructure during unintended circumstances--such as those posed by information warfare or by cascading software failures. Resolution of these questions is complicated by the lack of clear accountability of the private and the public sectors for the surety of telecommunications.

Impact of Distributed Energy Resources on the Reliability of Critical Telecommunications Facilities: Preprint  

DOE Green Energy (OSTI)

This paper documents a probabilistic risk assessment of existing and alternative power supply systems at a large telecommunications office. The analysis characterizes the increase in the reliability of power supply through the use of two alternative power configurations. Failures in the power systems supporting major telecommunications service nodes are a main contributor to significant telecommunications outages. A logical approach to improving the robustness of telecommunication facilities is to increase the depth and breadth of technologies available to restore power during power outages. Distributed energy resources such as fuel cells and gas turbines could provide additional on-site electric power sources to provide backup power, if batteries and diesel generators fail. The analysis is based on a hierarchical Bayesian approach and focuses on the failure probability associated with each of three possible facility configurations, along with assessment of the uncertainty or confidence level in the probability of failure. A risk-based characterization of final best configuration is presented.

Method and system for conserving power in a telecommunications network during emergency situations  

Science Conference Proceedings (OSTI)

Disclosed is a method and apparatus for conserving power in a telecommunications network during emergency situations. A permissible number list of emergency and/or priority numbers is stored in the telecommunications network. In the event of an emergency or power failure, input digits of a call to the telecommunications network are compared to the permissible number list. The call is processed in the telecommunications network and routed to its destination if the input digits match an entry in the permissible number list. The call is dropped without any further processing if the input digits do not match an entry in the permissible number list. Thus, power can be conserved in emergency situations by only allowing emergency and/or priority calls.

Hazmat Cam Wireless Video System  

SciTech Connect

This paper describes the Hazmat Cam Wireless Video System and its application to emergency response involving chemical, biological or radiological contamination. The Idaho National Laboratory designed the Hazmat Cam Wireless Video System to assist the National Guard Weapons of Mass Destruction - Civil Support Teams during their mission of emergency response to incidents involving weapons of mass destruction. The lightweight, handheld camera transmits encrypted, real-time video from inside a contaminated area, or hot-zone, to a command post located a safe distance away. The system includes a small wireless video camera, a true-diversity receiver, viewing console, and an optional extension link that allows the command post to be placed up to five miles from danger. It can be fully deployed by one person in a standalone configuration in less than 10 minutes. The complete system is battery powered. Each rechargeable camera battery powers the camera for 3 hours with the receiver and video monitor battery lasting 22 hours on a single charge. The camera transmits encrypted, low frequency analog video signals to a true-diversity receiver with three antennas. This unique combination of encryption and transmission technologies delivers encrypted, interference-free images to the command post under conditions where other wireless systems fail. The lightweight camera is completely waterproof for quick and easy decontamination after use. The Hazmat Cam Wireless Video System is currently being used by several National Guard Teams, the US Army, and by fire fighters. The system has been proven to greatly enhance situational awareness during the crucial, initial phase of a hazardous response allowing commanders to make better, faster, safer decisions.

In September 2007, U.S. Census Bureau researchers completed a third pilot study on factors that contribute to gaining cooperation and successfully completing survey interviews. This pilot study was part of a larger effort to systematically study interview dynamics and how they affect respondent cooperation with Census Bureau surveys. The results of this study will add to extant data on two previous pilot studies on gaining cooperation behavior (Beck, Wright, & Petkunas, 2007). In 2006, we collected data from Program Coordinators, Program Supervisors, and Senior Field Representatives (SFRs) working on (Beck, Wright, & Petkunas, 2007). The current pilot study involved collecting information from a sample of Census Bureau survey interviewers, called Field Representatives (FRs), throughout the United States. Like these other field employees, FRs work from one of the twelve Census Bureau Regional Offices, which are responsible for the management of field data collection. The FRs filled out a brief questionnaire asking them to list practices, techniques, and recommendations they felt were either successful or unsuccessful at gaining respondent cooperation with Current Population Survey (CPS) interviews. The CPS is a panel survey involving eight monthly interviews with each sampled household. Respondents complete four consecutive monthly interviews, rotate out

Impact of distributed energy resources on the reliability of a critical telecommunications facility.  

DOE Green Energy (OSTI)

This report documents a probabilistic risk assessment of an existing power supply system at a large telecommunications office. The focus is on characterizing the increase in the reliability of power supply through the use of two alternative power configurations. Telecommunications has been identified by the Department of Homeland Security as a critical infrastructure to the United States. Failures in the power systems supporting major telecommunications service nodes are a main contributor to major telecommunications outages. A logical approach to improve the robustness of telecommunication facilities would be to increase the depth and breadth of technologies available to restore power in the face of power outages. Distributed energy resources such as fuel cells and gas turbines could provide one more onsite electric power source to provide backup power, if batteries and diesel generators fail. The analysis is based on a hierarchical Bayesian approach and focuses on the failure probability associated with each of three possible facility configurations, along with assessment of the uncertainty or confidence level in the probability of failure. A risk-based characterization of final best configuration is presented.

Impact of SPS heating on VLF, LF, and MF telecommunications systems ascertained by experimental means  

DOE Green Energy (OSTI)

The results of experiments undertaken to assess the potential impact of the operation of the Satellite Power System on the D and E regions of the ionosphere, and on telecommunication systems that are dependent upon the structure of the lower ionosphere are summarized. Using the high-power high-frequency transmitter facility located at Platteville, Colorado, power densities comparable to the Satellite Power System can be delivered to the heights of 70 to 100 km above the surface of the earth. Observations of the performance of telecommunication systems that operate in the VLF, LF, and MF portions of the spectrum have been investigated during times when the ionosphere was modified with SPS comparable power density and when it was not. The results obtained indicte that the SPS, as currently configured with a peak power density of 23 mW/cm/sup 2/, will not adversely impact upon the performance of VLF, LF, and MF telecommunication systems.

Energy efficiency in wireless networks  

E-Print Network (OSTI)

Energy is a critical resource in the design of wireless networks since wireless devices are usually powered by batteries. Battery capacity is finite and the progress of battery technology is very slow, with capacity expected to make little improvement in the near future. Under these conditions, many techniques for conserving power have been proposed to increase battery life. In this dissertation we consider two approaches to conserving the energy consumed by a wireless network interface. One technique is to use power saving mode, which allows a node to power off its wireless network interface (or enter a doze state) to reduce energy consumption. The other is to use a technique that suitably varies transmission power to reduce energy consumption. These two techniques are closely related to theMAC (Medium Access Control) layer. With respect to power saving mode, we study IEEE 802.11 PSM (Power Saving Mechanism) and propose a scheme that improves its energy efficiency. We also investigate the interaction between power saving mode and TCP (Transport Control Protocol). As a second approach to conserving energy, we investigate a simple power control protocol, called BASIC, which uses the maximum transmission power for RTS-CTS and the minimum necessary power for DATA-ACK. We identify the deficiency of BASIC, which increases collisions and degrades network throughput, and propose a power control protocol that addresses these problems and achieves energy savings. Since energy conservation is not an issue limited to one layer of the protocol stack, we study a cross layer design that combines power control at the MAC layer and power aware routing at the network layer. One poweraware routing metric is minimizing the aggregate transmission power on a path from source to destination. This metric has been used along with BASIC-like power control under the assumption that it can save energy, which we show to be false. Also, we show that the power aware routing metric leads to a lower throughput. We show that using the shortest number of hops in conjunction with BASIC-like power control conserves more energy than power aware routing with BASIC-like power control.

Wireless Sensors Improve Data Center Efficiency  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Wireless Sensor Wireless Sensor Technology Overview In most buildings, space conditions are controlled and coordinated by a building automation system (BAS). A BAS can provide temperature visualization information with dashboard displays through a person-machine interface (PMI). However, in most data centers, space conditioning is achieved with multiple, independently-operating cooling units located within the space. Unfortunately, these data centers do not have adequate auto- mation systems or visualization tools to monitor or manage these cooling units efficiently. In 2001, an emerging technology was demonstrated at University of California, Davis by Dr. Raju Pandey that "meshed" temperature sensors into a network using wireless fidelity (Wi-Fi

Modern digital radio systems are complex and must be carefully designed, especially when expected to operate in harsh propagation environments. The ability to accurately predict the effects of propagation on wireless radio performance could lead to more efficient radio designs as well as the ability to perform vulnerability analyses before and after system deployment. In this report, the authors--experts in electromagnetic (EM) modeling and wireless communication theory--describe the construction of a simulation environment that is capable of quantifying the effects of wireless propagation on the performance of digital communication.

Epidemic Propagation In Overlaid Wireless Networks  

SciTech Connect

Witb tbe emergence of computer worms tbat can spread over air interfaces, wireless ad boc and sensor networks can be vulnerable to node compromises even if the deployed network is not connected to the backbone. Depending on the physical topology of the wireless network, even a single infected node can compromise the whole network. In this work, epidemic (e.g., worm) propagation in a static wireless network is studied, where a number of inCected mobile nodes are injected over the existing network. It is shown that the epidemic spread threshold and size depend on the physical topology of the underlying static wireless network as well as the mobility model employed by the infected mobile nodes. More specifically, results show that in a Cully-connected static wirelessnctwork targeted attacks are more effective, wbereas Cor a random topology random attacks can be sufficient to compromise the whole network.

Intrusion detection and monitoring for wireless networks.  

SciTech Connect

Wireless computer networks are increasing exponentially around the world. They are being implemented in both the unlicensed radio frequency (RF) spectrum (IEEE 802.11a/b/g) and the licensed spectrum (e.g., Firetide [1] and Motorola Canopy [2]). Wireless networks operating in the unlicensed spectrum are by far the most popular wireless computer networks in existence. The open (i.e., proprietary) nature of the IEEE 802.11 protocols and the availability of ''free'' RF spectrum have encouraged many producers of enterprise and common off-the-shelf (COTS) computer networking equipment to jump into the wireless arena. Competition between these companies has driven down the price of 802.11 wireless networking equipment and has improved user experiences with such equipment. The end result has been an increased adoption of the equipment by businesses and consumers, the establishment of the Wi-Fi Alliance [3], and widespread use of the Alliance's ''Wi-Fi'' moniker to describe these networks. Consumers use 802.11 equipment at home to reduce the burden of running wires in existing construction, facilitate the sharing of broadband Internet services with roommates or neighbors, and increase their range of ''connectedness''. Private businesses and government entities (at all levels) are deploying wireless networks to reduce wiring costs, increase employee mobility, enable non-employees to access the Internet, and create an added revenue stream to their existing business models (coffee houses, airports, hotels, etc.). Municipalities (Philadelphia; San Francisco; Grand Haven, MI) are deploying wireless networks so they can bring broadband Internet access to places lacking such access; offer limited-speed broadband access to impoverished communities; offer broadband in places, such as marinas and state parks, that are passed over by traditional broadband providers; and provide themselves with higher quality, more complete network coverage for use by emergency responders and other municipal agencies. In short, these Wi-Fi networks are being deployed everywhere. Much thought has been and is being put into evaluating cost-benefit analyses of wired vs. wireless networks and issues such as how to effectively cover an office building or municipality, how to efficiently manage a large network of wireless access points (APs), and how to save money by replacing an Internet service provider (ISP) with 802.11 technology. In comparison, very little thought and money are being focused on wireless security and monitoring for security purposes.

OIT Wireless Telemetry for Industrial Applications  

Science Conference Proceedings (OSTI)

The need for advanced wireless technology has been identified in the National Research Council publication (1) ''Manufacturing Process Controls for the Industries of the Future as a Critical Technology for the Future''. The deployment challenges to be overcome in order for wireless to be a viable option include: (1) eliminating interference (assuring reliable communications); (2) easing the deployment of intelligent, wireless sensors; (3) developing reliable networks (robust architectures); (4) developing remote power (long-lasting and reliable); and (5) developing standardized communication protocols. This project demonstrated the feasibility of robust wireless sensor networks that could meet these requirements for the harsh environments common to the DOE/OIT Industries of the Future. It resulted in a wireless test bed that was demonstrated in a paper mill and a steel plant. The test bed illustrated key protocols and components that would be required in a real-life, wireless network. The technologies for low power connectivity developed and demonstrated at the plant eased fears that the radios would interfere with existing control equipment. The same direct sequence, spread spectrum (DSSS) technology that helped assure the reliability of the connection also demonstrated that wireless communication was feasible in these plants without boosting the transmitted power to dangerous levels. Our experience and research have indicated that two key parameters are of ultimate importance: (1) reliability and (2) inter-system compatibility. Reliability is the key to immediate acceptance among industrial users. The importance cannot be overstated, because users will not tolerate an unreliable information network. A longer term issue that is at least as important as the reliability of a single system is the inter-system compatibility between these wireless sensor networks and other wireless systems that are part of our industries. In the long run, the ability of wireless sensor networks to operate cooperatively in an environment that includes wireless LANs, wireless headsets, RF heating, wireless crane controls and many other users of the electromagnetic spectrum will probably be the most important issue we can address. A network of units (Figure 1) has been developed that demonstrates the feasibility of direct-sequence spread spectrum wireless sensor networking for industrial environments. The hardware consists of a group of reprogrammable transceivers that can act as sensor nodes or network nodes or both. These units and the team that built them are the heart of a test bed development system that has been used successfully in demonstrations at various industrial sites. As previously reported, these units have been successfully tested at a paper mill. More recently, these units were utilized in a permanent installation at a steel mill. Both of these applications demonstrated the ease with which a new network could be installed, and the reality that DSSS units can operate successfully in plants where narrow band transmitters had previously caused interference with plant operations.

Mining Web hyperlink data for business information: The case of telecommunications equipment companies  

E-Print Network (OSTI)

Few studies have explored the possibility of mining Web hyperlink data for e-commerce or business information. This study is an attempt to fill this gap. The project selected a group of telecommunications equipment companies and collected data on the number of links pointing to the company Websites (inlinks) and the companys revenue. A significant correlation between the two variables was found, suggesting that inlinks contain useful business information and can be objects for Web data mining. The project then explored the feasibility of using Web co-link data to map business competition positions. Co-link data (links pointing to a pair of company Websites) were collected and analyzed using multidimensional scaling (MDS). MDS maps correctly clustered these companies into sectors of the telecommunications equipment industry. Data collection was repeated after nine months and the results confirmed the reliability of the methodology developed in the study. 1.

Laying the Groundwork: Lessons Learned from the Telecommunications Industry for Distributed Generation; Preprint  

SciTech Connect

The telecommunications industry went through growing pains in the past that hold some interesting lessons for the growing distributed generation (DG) industry. The technology shifts and stakeholders involved with the historic market transformation of the telecommunications sector mirror similar factors involved in distributed generation today. An examination of these factors may inform best practices when approaching the conduits necessary to accelerate the shifting of our nation's energy system to cleaner forms of generation and use. From a technical perspective, the telecom industry in the 1990s saw a shift from highly centralized systems that had no capacity for adaptation to highly adaptive, distributed network systems. From a management perspective, the industry shifted from small, private-company structures to big, capital-intensive corporations. This presentation will explore potential correlation and outline the lessons that we can take away from this comparison.

Wang OIS glossary package for reformatting documents telecommunicated to the OIS system  

SciTech Connect

Documents that are composed on a computer and then transmitted by telecommunications into a Wang Office Information System (OIS) word processing system need to be reformatted and cleaned up before they can be used properly as word processing documents suitable for further revisions or additions. This report describes a group of glossary entries created for the Wang OIS which simplifies the job of cleaning up telecommunicated documents. This glossary is a semi-automated process designed to eliminate most of the tedious work needed to be performed in removing extra spaces and returns, adjusting formats, moving material, repagination, using tabs or indents, and similar problems. The report briefly discusses the problems, describes the glossary approach to solving them, and gives instructions for actually using the glossary entries.

We perform the first demonstration of a quantum interface for frequency down-conversion from visible to telecommunication bands by using a nonlinear crystal. This interface has a potential to work over wide bandwidths, leading to a high-speed interface of frequency conversion. We achieve the conversion of a pico-second visible photon at 780 nm to a 1522-nm photon, and observe that the conversion process retain entanglement between the down-converted photon and another photon.

Wireless Demand Response Controls for HVAC Systems  

Science Conference Proceedings (OSTI)

The objectives of this scoping study were to develop and test control software and wireless hardware that could enable closed-loop, zone-temperature-based demand response in buildings that have either pneumatic controls or legacy digital controls that cannot be used as part of a demand response automation system. We designed a SOAP client that is compatible with the Demand Response Automation Server (DRAS) being used by the IOUs in California for their CPP program, design the DR control software, investigated the use of cellular routers for connecting to the DRAS, and tested the wireless DR system with an emulator running a calibrated model of a working building. The results show that the wireless DR system can shed approximately 1.5 Watts per design CFM on the design day in a hot, inland climate in California while keeping temperatures within the limits of ASHRAE Standard 55: Thermal Environmental Conditions for Human Occupancy.

Over the last several years, my company has been supplying many service companies with wireless dispatching solutions. Recently the impact of the system has been greatly increased with the introduction of a GPS (Global Position Systems) interface. This adds visual recognition as to the whereabouts of each vehicle within the customer service area. The only equipment required in the field for GPS is a transmit/receive device and a wireless modem, one mounted out of the way in the vehicle (under the seat) and a {open_quotes}hockey puck{close_quotes} size unit on the roof of the vehicle. The GPS received unit and wireless modem are used to retrieve the longitude, latitude and ground speed coordinates and transmit them back to the host system.

ULTRA SECURE HIGH RELIABILITY WIRELESS RADIATION MONITOR  

SciTech Connect

Radiation monitoring in nuclear facilities is essential to safe operation of the equipment as well as protecting personnel. In specific, typical air monitoring of radioactive gases or particulate involves complex systems of valves, pumps, piping and electronics. The challenge is to measure a representative sample in areas that are radioactively contaminated. Running cables and piping to these locations is very expensive due to the containment requirements. Penetration into and out of an airborne or containment area is complex and costly. The process rooms are built with thick rebar-enforced concrete walls with glove box containment chambers inside. Figure 1 shows high temperature radiation resistance cabling entering the top of a typical glove box. In some case, the entire processing area must be contained in a 'hot cell' where the only access into the chamber is via manipulators. An example is shown in Figure 2. A short range wireless network provides an ideal communication link for transmitting the data from the radiation sensor to a 'clean area', or area absent of any radiation fields or radioactive contamination. Radiation monitoring systems that protect personnel and equipment must meet stringent codes and standards due to the consequences of failure. At first glance a wired system would seem more desirable. Concerns with wireless communication include latency, jamming, spoofing, man in the middle attacks, and hacking. The Department of Energy's Savannah River National Laboratory (SRNL) has developed a prototype wireless radiation air monitoring system that address many of the concerns with wireless and allows quick deployment in radiation and contamination areas. It is stand alone and only requires a standard 120 VAC, 60 Hz power source. It is designed to be mounted or portable. The wireless link uses a National Security Agency (NSA) Suite B compliant wireless network from Fortress Technologies that is considered robust enough to be used for classified data transmission in place of NSA Type 1 devices.

Iterative Collision Resolution in Wireless Networks  

E-Print Network (OSTI)

With the growing popularity of smart phones and tablets, development of multimedia applications is on the rise. Speedy transmission of this massive amount information is already pushing the limits of the capacity of wireless networks, and in upcoming years wireless data traffic is projected to continue increasing dramatically. Advances in wireless network throughput are necessary to keep up with societys data demands. In an uncoordinated wireless communications system, transmissions collide and interfere as multiple users transmit data to a central receiver. Slotted-ALOHA, the conventional method that schedules user transmissions, has only 37% throughput efficiency. However, theoretical results in recent studies suggest that scheduling transmissions over a number of random, fixed timeslots and employing iterative collision resolution techniques achieves optimal throughput efficiency of approximately 100%. This research considers how real-world conditions affect these theoretical results. A MATLAB model was developed create random graphs, representing users transmitting packets over such timeslots, and the packets were resolved by this method. This model was simulated extensively, representing networks of up to 10,000 users over 10,000 to 15,000 timeslots, and the number of packets resolved in each iteration was measured. These simulations have generated empirical data that backs up the theoretical claim. The distribution of the number of packets resolved also led to modifications of the current model to increase the percentage of packets resolved in each iteration. Furthermore, by investigating low density parity check coding techniques, other modifications to the current model can optimize the throughput over several consecutive transmissions where unresolved packets are resent with higher probability of recovery. These results demonstrate the potential of this method in handling uncoordinated transmissions in communications systems, even in the presence of finite conditions. This suggests that this method could eventually be employed in actual wireless systems.

Auction-based Bandwidth Allocation Mechanisms for Wireless Future Internet  

E-Print Network (OSTI)

An important aspect of the Future Internet is the efficient utilization of (wireless) network resources. In order for the - demanding in terms of QoS - Future Internet services to be provided, the current trend is evolving towards an "integrated" wireless network access model that enables users to enjoy mobility, seamless access and high quality of service in an all-IP network on an "Anytime, Anywhere" basis. The term "integrated" is used to denote that the Future Internet wireless "last mile" is expected to comprise multiple heterogeneous geographically coexisting wireless networks, each having different capacity and coverage radius. The efficient management of the wireless access network resources is crucial due to their scarcity that renders wireless access a potential bottleneck for the provision of high quality services. In this paper we propose an auction mechanism for allocating the bandwidth of such a network so that efficiency is attained, i.e. social welfare is maximized. In particular, we propose a...

Beyond telecommuting: A new paradigm for the effect of telecommunications on travel  

Science Conference Proceedings (OSTI)

Conventional wisdom about social and economic behavior holds that the use of telecommunications is a natural substitute for transportation. For example, telephone calls can replace travel to meetings, and facsimile or electronic-mail transmission of documents substitutes for courier or postal delivery. The moving of information can replace the moving of period and goods. Vehicle traffic on the national transportation infrastructure can be replaced by digital traffic on what is now called the National Information Infrastructure (NII). A leading example is telecommuting. This means using telecommunications to replace commuting between home and work. Telecommuting is an optional way of expanding employees` work locations in those circumstances where it yields both improved organizational performance and employee satisfication. Telecommuting accounts for 7.6 million U.S. workers as of early 1993, up 15% from the 6.6 million counted in 1992. The growth of telecommuting has been strong for the past five years. No one has identified any reasons to suggest that this growth will abate in the forseeable future.

Political Embeddedness, Executive Autonomy, Corporate Characteristics, and Financial Malfeasance in Large Telecommunications Companies  

E-Print Network (OSTI)

This thesis examines the causes of financial malfeasance in the largest U.S. telecommunications corporations between 1995 and 2004. Specifically, it examines whether or not the executive compensation package influences the likelihood that a corporation will falsify its financial statements. The methods used are both qualitative and quantitative. I approach the question form a historical point of view and attempt to identify certain salient characteristics within the telecommunications industry that may influence of unethical or illegal activity. The findings support organizational-political embeddedness theory, which suggests that differential social structures create dependencies, incentives, and opportunities to engage in financial malfeasance. The historical analysis shows that neoliberal policies enacted in the mid-1990s resulted in organizational and political structures that permitted managers to engage in financial malfeasance while limiting the efficiency of regulatory bureaucracies. The quantitative analysis yields mixed findings, many of which are consistent with previous research on white-collar crime and financial malfeasance. This article adds to existing literature by outlining significant public policy shifts and the results those shifts may have on specific industries. These findings have important implications for political officials and corporate oversight organizations.

X-by-wireless: a novel approach to vehicle control  

E-Print Network (OSTI)

As the cost of wireless devices approaches zero, it becomes more feasible to replace wires with wireless communication. Vehicle wiring harnesses are traditionally wired to communicate both power and information simultaneously, resulting in separate circuits for each vehicle device. X-By-Wireless seeks to supplant this configuration in favor of a shared power bus and wireless inter-component communication. In doing so, we can recognize a number of benefits such as reduced weight and increased reliability, flexibility, and upgradeability. However, this introduces new problems such as longer transmission delays, interference and encryption issues, fusing difficulties, and public perception regarding safety. The purpose of this thesis is to define the X-By-Wireless concept and to investigate the benefits and drawbacks in implementing X-By-Wireless. Furthermore, we do a theoretical and case study analysis to expand upon the weight reduction benefit so as to quantify the expected improvements. We also address each of the challenges presented by X-By-Wireless and integrate them into a proposed circuit that is capable of performing all the necessary functions of wireless control, wireless sensing, and fusing. We find that the proposed device can be mass-produced as an effective solution that meets the speed and security constraints necessary for most vehicle components.

Analyzing Options for Airborne Emergency Wireless Communications  

SciTech Connect

In the event of large-scale natural or manmade catastrophic events, access to reliable and enduring commercial communication systems is critical. Hurricane Katrina provided a recent example of the need to ensure communications during a national emergency. To ensure that communication demands are met during these critical times, Idaho National Laboratory (INL) under the guidance of United States Strategic Command has studied infrastructure issues, concerns, and vulnerabilities associated with an airborne wireless communications capability. Such a capability could provide emergency wireless communications until public/commercial nodes can be systematically restored. This report focuses on the airborne cellular restoration concept; analyzing basic infrastructure requirements; identifying related infrastructure issues, concerns, and vulnerabilities and offers recommended solutions.

Fundamental Tradeoffs on Green Wireless Networks  

E-Print Network (OSTI)

Traditional design of mobile wireless networks mainly focuses on ubiquitous access and large capacity. However, as energy saving and environmental protection become a global demand and inevitable trend, wireless researchers and engineers need to shift their focus to energy-efficiency oriented design, that is, green radio. In this paper, we propose a framework for green radio research and integrate the fundamental issues that are currently scattered. The skeleton of the framework consists of four fundamental tradeoffs: deployment efficiency - energy efficiency tradeoff, spectrum efficiency - energy efficiency tradeoff, bandwidth - power tradeoff, and delay - power tradeoff. With the help of the four fundamental tradeoffs, we demonstrate that key network performance/cost indicators are all stringed together.

Wireless Information Transfer with Opportunistic Energy Harvesting  

E-Print Network (OSTI)

Energy harvesting is a promising solution to prolong the operation of energy-constrained wireless networks. In particular, scavenging energy from ambient radio signals, namely wireless energy harvesting (WEH), has recently drawn significant attention. In this paper, we consider a point-to-point wireless link over the flat-fading channel subject to the time-varying co-channel interference. It is assumed that the receiver has no fixed power supplies and thus needs to replenish energy via WEH from the unintended interference and/or the intended signal sent by the transmitter. We further assume a single-antenna receiver that can only decode information or harvest energy at any given time due to the practical circuit limitation. As a result, it is important to investigate when the receiver should switch between the two modes of information decoding (ID) and energy harvesting (EH), based on the instantaneous channel and interference conditions. In this paper, we derive the optimal mode switching rule at the receive...

Experimental Analysis of Heterogeneous Wireless Networks  

E-Print Network (OSTI)

Packet loss and delay in Internet degrade the quality of requested services like VoIP (Voice over IP) or Video Streaming. In novel network scenarios where wired and wireless connections are melted together, a real measure of these parameters is fundamental in a planning process of new services over novel network infrastructures. Nowadays networks are heterogeneous in terms of access network technologies (wired LAN Ethernet 10/100/1000, Wireless LAN - 802.11a, 802.11b, 802.11g -, GPRS, UMTS, GSM, Bluetooth, ...), end-users' devices (workstation, PC desktop, Laptop/Notebook, PDA, Advanced Mobile Phone, ...) and finally operating systems (Unix, Linux, Win 98/NT/2000/XP, Win CE, Linux Familiar, OS Embedded, ...). In this work we provide a heterogeneous network performance characterization with respect to delay and throughput in UDP and TCP environments. In order to determine our results we use an innovative traffic generator named D-ITG (Distributed Internet Traffic Generator). Results presented in this paper can be used as performance references for development of wireless communication applications over multiservice and heterogeneous networks.

Characterizing the IEEE 802.11 Traffic: The Wireless Side  

E-Print Network (OSTI)

Many studies on measurement and characterization of wireless LANs have been performed recently. Most of these measurements have been conducted from the wired portion of the network based on wired monitoring or SNMP statistics. In this paper we argue that traffic measurements from a wireless vantage point in the network are more appropriate than wired measurements or SNMP statistics, to expose the wireless medium characteristics and their impact on the traffic patterns. While it is easier to make consistent measurements in the wired part of a network, such measurements can not observe the significant vagaries present in the wireless medium itself. As a consequence constructing an accurate measurement system from a wireless vantage point is important but usually quite difficult due to the noisy wireless channel. In our work we have explored the various issues in implementing such a system to monitor traffic in an IEEE 802.11 based wireless network. We show the effectiveness of the wireless monitoring by quantitatively comparing it with SNMP and measurements at wired vantage points. We also show the analysis of a typical computer science department network traffic using the wireless monitoring technique. Our analysis reveals rich information about the PHY/MAC layers of the IEEE 802.11 protocol such as the typical traffic mix of different frame types, their temporal characteristics, correlation with the user activities and the error characteristics of the wireless medium. Moreover, we identify anomalies in the operation of the IEEE 802.11 MAC protocol. Our results show excessive retransmissions of some management frame types reducing the useful throughput of the wireless network. We also find that some features of the protocol, which were designed to reduce the retransmissi...

Western Region Renewable Energy Markets: Implications for the Bureau of Land Management  

SciTech Connect

The purpose of this analysis is to provide the U.S. Department of the Interior (DOI) and the Bureau of Land Management (BLM) with an overview of renewable energy (RE) generation markets, transmission planning efforts, and the ongoing role of the BLM RE projects in the electricity markets of the 11 states (Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming) that comprise the Western Electricity Coordinating Council (WECC) Region. This analysis focuses on the status of, and projections for, likely development of non-hydroelectric renewable electricity from solar (including photovoltaic [PV] and concentrating solar power [CSP]), wind, biomass and geothermal resources in these states. Absent new policy drivers and without the extension of the DOE loan guarantee program and Treasury's 1603 program, state RPS requirements are likely to remain a primary driver for new RE deployment in the western United States. Assuming no additional policy incentives are implemented, projected RE demand for the WECC states by 2020 is 134,000 GWh. Installed capacity to meet that demand will need to be within the range of 28,000-46,000 MW.

Power management and power control in wireless networks

With the proliferation of portable computing platforms and small wireless devices, wireless networks have received more and more attention as a means for providing data communications among devices regardless of their physical locations. However, due to the slow advancement in battery technology, battery power continues to be a constrained resource in wireless networks and thus energy conservation remains to be an important issue. In this book chapter, we provide a taxonomy of power management and power control algorithms and protocols for wireless networks. We start with a description of energy consumption characteristics of wireless devices, and identify the power consumed in the wireless transmitters essentially consists of two parts: power consumed by the radio electronic and power consumed in the RF output. To save power, one can either turn off the radio electronic and put wireless devices into the power saving mode at appropriate times, or adjust the RF output power (and hence the wireless transmission range) subject to maintaining network connectivity and bi-directionality. The former techniques are termed as power management, while the latter power

Quantum frequency conversion of quantum memory compatible photons to telecommunication wavelengths  

E-Print Network (OSTI)

We report an experiment demonstrating quantum frequency conversion of weak light pulses compatible with atomic quantum memories to telecommunication wavelengths. We use a PPLN nonlinear waveguide to convert weak coherent states at the single photon level with a duration of 30ns from a wavelength of 780nm to 1552nm. We measure a maximal waveguide internal (external) conversion efficiency eta_int = 0.41 (eta_ext = 0.25), and we show that the signal to noise ratio (SNR) is good enough to reduce the input photon number below 1. In addition, we show that the noise generated by the pump beam in the crystal is proportional to the spectral bandwidth of the device, suggesting that narrower filtering could significantly increase the SNR. Finally, we demonstrate that the quantum frequency converter can operate in the quantum regime by converting a time-bin qubit and measuring the qubit fidelity after conversion.

ADVANCED WIRELESS CHARGING SYSTEM FOR PORTABLE ELECTRIC DEVICES  

E-Print Network (OSTI)

This paper presents a wireless charging system for portable electric devices. The important impacts of wireless charging systems on the global environment are first examined, and the two basic methods for wireless charging are then explained. The feasibility of applying each method to the wireless charging system is also analyzed. In order to achieve a high efficiency and more precise control for the wireless power transfer, the technology of a contactless charging board is used in this research. Because the experiments operated base on an induction cooker, the basic structure of the induction cooker are explained. Then the strategy of controling the output power is given. Finally, comprehensive experiments with efficiency tests, effective distance tests, and how the location of the coil would affect those important factors are given. The result shows that the method of contactless charging board is reliable for portable electric devices to achieve a relatively high charging efficiency and an acceptable charging distance.
