摘要：
The power supply interruption and the destruction of communications infrastructure in the event of wide area disasters make it difficult to communicate urgent information such as disaster situation and safety information. DTN (Delay Tolerant Network), which is an infrastructure-less communication technique, is one of the solution methods. However DTN has a problem of power consumption in order to realize information communication in a wide area disaster. The evacuees are assumed to communicate with others by their own mobile terminals in the disaster-stricken areas. Since these terminals have limited electric power, it is preferable to use a communication method considering power usage efficiency. In this paper, we propose a disaster-time communication system using a message ferry method for exchanging and collecting disaster situation and safety information. Also, in order to improve the power usage efficiency of the network on the proposed system, we propose and evaluate a method to efficiently utilize electric power for communication by setting multistage threshold for power remaining.
