Quick, accurate damage assessment information. is necessary for speedy and effective rescueresponse in the aftermath of a large natural disaster or man-made disaster. Nevertheless, communications systems could not work sufficiently in several past cases due to communicationscongestion, damage on the system and power depletion. As a result, response efforts were delayed, causing further damage that could have been prevented with better communications. This paper, first, describes current communications and monitoring systems in a disaster, then, shows the outline of adamage information collection system with ad hoc networking techniques. The monitoring system isorganized with sensor networks and access network. The former is charged to detect damage conditionsof a building and victims trapped beneath rubble in a disaster site. The latter is to maintaincommunications between a center station and nodes deploying in a citywide range. The paper furtherdiscusses a scheme for power-aware operation of networking devices to be operable for at least 72 hourseven in power outage conditions in a disaster.
