Autonomous Community Architecture for Emergency Information's Transmission

摘要

Wireless Sensor Network (WSN) is widely used in Emergency Management System(EMS) to assure requirement of safety in current society. When emergency happens, real-timely transmitting emergency information 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 real-time transmission of emergency information, autonomous community architecture 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 real-time property of emergency information.
