Evaluation of Wireless Network Communication by Autonomous Flight Wireless Nodes for Resilient Networks

摘要

The recent development of the society has caused new types of problems such as gaps of depopulation, population aging, and income between urban areas and local areas. The gap of communication networks is also one of the problems, and the poor network circumstance in local areas might affect the future medicare or welfare services by using Information Technology. Also, when there is a natural disaster such as earthquakes or typhoon, these local areas are likely to isolate from others because of disconnection of communication cables or breakdown of network devices. Therefore, this paper proposes Autonomous Flight Wireless Nodes (AFW) for the resilient networks consisted of Delay Tolerant Networks and Never Die Networks, and it is aiming to communicate with isolated areas. In the proposed methods, IP network based drones support data transmission by the autonomous flight with seeking possible wireless stations and sending the message data by the proposed resilient network. Then, the implementations of the proposed methods are introduced, and the results of wireless network conditions by the field experiments are reported in this paper.
