Abstract
This paper propose a novel deployment method of Wireless Mesh Network (WMN) using a group of mobile robots equipped with a wireless transceiver. Our proposed method utilize rough relative positions of the robots estimated by Radio Signal Strength Indicators (RSSI) to deploy WMN. Our algorithm is consist of following two parts; (1) Fully distributed and dynamic role decision method among robots and (2) Adaptive direction control using time difference of RSSI. In this research, we evaluate performance of proposed and conventional methods which use RSSI at simulated disaster area including radio-wave propagation and wireless communication protocol models. As a result of simulations and real robots experiments, our proposed method outperformed conventional methods in aspects of required deployment time and traveled distance of the robots.
