Research and Implementation of WSN in Fire Safety Applications

Applying WSN (wireless sensor networks) technology to the fire safety can actualize wireless requirement, network, and intelligent fire monitoring. A wireless fire detection system based on WSN was described in the thesis, which can acquire data of temperature and smoke concentration. Fire detection nodes using SOC CC2430 as the control unit to realize the communication between nodes, the software running on the nodes applies CSMA/CA Medium Access Control protocol and a shortest path routing algorithm for data transmission in multi-hop. The Gateway is designed an implemented based on ARM9 and Linux, which connects wireless fire detection network and the Internet, it has a strong processing, storage and network communication capabilities. Remote users may share real-time fire parameter from Internet which connects with the wireless fire data acquisition network through the Gateway.
