摘要

广域灾害发生时，电力供应中断，通信基础设施遭到破坏，给灾情、安全信息等紧急信息的传递带来困难。DTN (Delay tolerance Network)是一种无基础设施的通信技术，是解决这一问题的方法之一。然而，为了在大范围灾害中实现信息通信，DTN存在功耗问题。假设撤离人员通过自己的移动终端与灾区的其他人进行通信。由于这些终端的电力有限，因此最好采用考虑电力使用效率的通信方法。在本文中，我们提出了一种灾害时通信系统，使用消息轮渡方法交换和收集灾情和安全信息。此外，为了提高系统的电力使用效率，我们提出并评估了一种通过设置多阶段剩余电力阈值来有效利用通信电力的方法。

A temporary communication system using DTN for improving power consumption of mobile terminals

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.
