An Ad-hoc Wireless Sensor Network Protocol for Disaster Management

抄録

On the way of ubiquitous or pervasive computing, now many researchers are working on Wireless Sensor Network and RFID integration for emergency disaster management. If we can use cellular network after disaster for rescue, in that case, it is easy to identify the survivors' locations. But in almost every case, after an enormous disaster, many Base stations are unable to communicate due to their destructions. From the experience, the cellular phone could not be used even due to the Nakagoshi earthquake in Japan. In this paper, we present an ad-hoc wireless sensor network (WSN) protocol to overcome this deficiency. In our considering network infrastructure, we assume survivors carrying mobiles, tagged with RFID tag. There are some sensor nodes in every cell of a cellular network. Normally these nodes only read periodic messages from their corresponding base station. After any disaster, if these nodes are unable to communicate with their base station, they will able to understand the occurrence of disaster and will from an ad-hoc network. In ad-hoc network, every sensor node will try to find out RFID tagged mobile users (survivors) to disseminate their locations' information to the ad-hoc network to make these available to rescuers.
