Wireless sensor networks for fire emergency and gas detection

Environmental monitoring applications require adept networking strategies and reliable communications to ensure the integrity of their most fundamental operations including the sensing duties, network-node interactions, and system resiliency to unpredictable events. In this paper, we propose a fire emergency and gas detection system based on WSNs for both indoor and outdoor environments. The challenges which are addressed in this paper include: management of nodes, provision of algorithms, risk modeling and analysis, and Over-The-Air-Programming (OTAP).
