| Abstract(in English) | In mobile sensing where autonomous mobile robots equipped with sensors perform sensing operations over a sensing field, the number and positions of sensing targets are unknown, therefore, robots need to search sensing targets by themselves. In order to realize an efficient search with a group of robots, an algorithm called mobile sensing cluster has been proposed, where robots form a swarm with data exchange through wireless communications. In the mobile sensing cluster considered in this paper, the positions of the sensing targets are estimated based on RSSI (Received Signal Strength Indicator) of radio waves emitted from the sensing targets. In this paper, we focus on propagation environment of radio waves received from the sensing targets. In realistic environments where many obstacles exit, the radio signals are influenced by shadowing and fading, and the RSSI variation of radio waves received by robots does not depend only on the distance. In this case, the RSSI fluctuates randomly, and it is expected that the robot cannot properly estimate the positions of the sensing targets, which decreases its search efficiency. Therefore, in this paper, by computer simulation, we investigate the impact of wireless signal propagation on the search efficiency of mobile sensing cluster. |
