Autonomous Emergency Information Transmittion Technology through Community Coordination to Achieve Real-Time in In Wireless Sensor Network System

Wireless Sensor Network (WSN) is widely used in Emergency Management System (EMS) to assure requirement of safety in current society. For centralized management, it is difficult for conventional systems to assure the real-time transmission of emergency information under rapidly changing situations. Thus, based on the Autonomous Decentralized Community (ADC) concept the main route for emergency information transmission and the barrier for protecting the main route has been proposed. However, when multiple emergencies happen, the real-time property will decease for the transmission collision between communities. Therefore, this paper proposes Autonomous Emergency Information Transmission Technology in which the communities autonomously coordinate with each other to avoid the transmission collision between the main routes. The simulation results show the improvement of proposed technology.
