Recently, Wireless Sensor Network (WSN) technology has been widely used in various fields such as public safety applications since it provides a wide range of surveillance and monitoring applications with an inexpensive price. In this paper, we investigate the use of wireless sensor network technology for fire detection and rescue system. We propose a framework, which can detect fires promptly and support rescue activities, using wireless sensor devices. Our framework consists of fire detection sensor network, information gathering layer, middleware, and escape support system. We have implemented a test-bed and evaluated the performance of fire detection via experiments.
