Development of Robot Wireless Sensor Networks Construction Method Referring to Throughput Stability

Abstract

We have discussed Robot Wireless Sensor Networks (RWSN) construction method for expanding tele-operation area by using mobile robot in post-disaster underground space. In RWSN construction method, mobile robots carry wireless sensor nodes (SNs) and deploy them into the environment. Deployed SNs construct wireless sensor networks by Ad-Hoc connection. In RWSN construction, a wireless communication quality measurement is important to keep connection of communication between the mobile robot and an operator. However, it takes time to construct RWSN utilizing the existing method. Therefore, we developed SNs deployment method utilizing low communication load throughput to propose shortening RWSN construction time. In this paper, we evaluated the proposed method, then it is confirmed that maintaining communication connectivity and shortening RWSN construction time.
