Autonomous Community Construction Technology for Timely Transmitting Emergency Information

Wireless Sensor Network(WSN) is widely used in Emergency Management System(EMS) to assure requirement of safety in current society. When emergency happens, timely transmitting emergency information in changing environment should be assured. But this requirement can not be satisfied by conventional approaches which are based on static situations and centralized management. In this paper, to assure timely transmitting emergency information in dynamic changing environment, autonomous community construction technology is proposed to construct a special group of routers, called community which includes main route for emergency information´s transmission, and barrier which protects Emergency information´s transmission from influence of normal sensing information´s transmission. The evaluation results indicate improvement of timeliness by proposed technology.
