Information Sharing System Adapted to Disaster Phase

In recent years, the number of natural disasters in Japan has been increasing, and research on information sharing during disasters has been carried out. However, most of the previous research have limited the function of the system to the time of disaster. In this paper, we propose a system that is used in daily life and also adapt to the times of disaster. We set up disaster phase based on the damage assumption of the Cabinet Office in Japan and implement a system according to that phase. Several experiments are conducted with an important feature, Mobile Ad-hoc Network with Bluetooth.
