  1. Data Flow/Tool Chains A large amount of sample data are greatly needed in a timely manner. Firebug tool chains handle the data flow with standard technology, make the data with accurate data value, reliable data transfer and world wide access of data. Abstract Collecting real time data from wildfires is important for life safety considerations, and allows predictive analysis of evolving fire behavior. One way to collect such data is to deploy sensors in the wild fire environment. FireBugs are small, wireless sensors (motes) based on TinyOS that self-organize into networks for collecting real time data in wild fire environments. The FireBug system combines state-of-the-art sensor hardware running TinyOS with standard, off-the-shelf World Wide Web and database technology for allowing users to rapidly deploy FireBugs and monitor network behavior. System Architecture The FireBug system is composed of a network of GPS-enabled, wireless thermal sensors, a control layer for processing sensor data, and a command center for interactively communicating with the sensor network. Each of these layers are independent of the others, communicating through well-defined interfaces. GPS Sensor location is an essential component of instrumented wildfire monitoring. Each mote is equipped with a Leadtek GPS receiver. Following deployment, the mote’s fixed global position (GGA) is recorded and stored locally. Multi-hop Routing Protocol The initial implementation of FireBug uses MH6 for the self-organizing network routing protocol. Motes route data to the base station using radio link reliability. Implementation • Fire Board/Mote • Each mote has sufficient power, radio communication and processing capabilities to support location and thermal sensors and data handling. Along with geographic position, motes measure: • •Humidity • •Temperature • •Light Intensity • •Acceleration Acknowledgments The FireBug system was funded by a grant from the National Science Foundation Information Technology Research initiative, award ITR/IM-0121693.
