1. Introduction
Several sensor applications have been developed over the last few years to monitor
environmental properties such as temperature and humidity. One of the most important
requirements for these monitoring applications is being unobtrusive, which creates a need
for wireless ad-hoc networks using very small sensing nodes. These special networks are
called wireless sensor networks (WSN). WSNs are built from many wireless sensors in a
high-density configuration to provide redundancy and to monitor a large physical area.
WSNs can be used to detect traffic patterns within a city by tracking the number of vehicles
using a designated street (Winjie et al., 2005), (Tubaishat et al., 2008). If an emergency arises,
the network can relay the information to the city hall and notify police, fire, and ambulance
drivers of congested streets. An application could even be designed that suggests the fastest
route to the emergency area. When compared to computer terminals in Local Area
Networks (LANs), wireless sensors must operate on very low capacity batteries to minimize
