Construction Strategy of Wireless Sensor Networks with Throughput Stability by Using Mobile Robot

Abstract

We propose a wireless sensor networks deployment strategy for constructing wireless communication infrastructures for a rescue robot with considering a throughput between sensor nodes (SNs). Recent studies for reducing disaster damage focus on a disaster area information gathering in underground spaces. Since information gathering activities in such post disaster underground spaces present a high risk of personal injury by secondary disasters, a lot of rescue workers were injured or killed in the past. Because of this background, gathering information by utilizing the rescue robot is discussed in wide area. However, there are no wireless communication infrastructures for tele-operation of rescue robot in the post-disaster environment such as the underground space. Therefore, we have been discussing the construction method of wireless communication infrastructures for remotely operated the rescue robot by utilizing the rescue robot. In this paper, we evaluated the proposed method in field operation test, and then it is confirmed that maintaining communication connectivity and throughputs between End to End of constructed networks.
