A Disaster Information Sharing Method by the Mobile Servers in Challenged Networks

Each local government provides a sharing system of disaster area information and safety information at a disaster. However, when a large-disaster occurs, disaster information system may not be available in the situation that a communication infrastructure was destroyed. In this study, we propose the disaster information system that is usually changes two kind of reporting methods at time and a disaster. In addition, the information dispatch from a stricken area at the time of disaster is enabled in the proposed system. That is because mobile server relays the data that occurred from disaster information system.
