Summary: Koala + Phoenix
Koala is a data-collection system for TinyOS. Sensor nodes periodically sample their sensors,
delta-compress the data, and store it to external flash. Periodically, a basestation PC is used to
wake up the nodes, establish multi-hop paths to them, and retrieve the buffered data.
This distribution also integrates the Phoenix time reconstruction algorithm. Sensor nodes
periodially exchange time-state information. After data is collected, this information can be used
to map measurements (timestamped in node-local time) to a global timeframe (provided by a
GPS or PC clock).

The source code for the Koala data collection system is available via git from
git clone git://hinrg.cs.jhu.edu/git/carlson/tinyos-2.x.git
You can browse the repository here . This repository includes the core tinyos 2.x distribution,
the Koala sensing node software, basestation node software, python download scripts, data
upload application, and a template SQL Server database. Setup instructions can be found
under the apps/Koala directory in this repository. Please note that the SQL Server databases
make this a rather hefty download.
