Abstract
An algorithm based on Received Signal Strength Indicator (RSSI) is designed for locating a wireless signal source in Multi-Robot System (MRS). Mobile robots are initially assigned to different locations. They are either sending or sensing wireless signals. The purpose of the algorithm is to establish communication among robots by locating the signal sources. Three main behavior modes of a robot are proposed for the algorithm skeleton through behavior-based analyzing. A log-distance path loss model is adopted for representing Received Signal Strength Indicator (RSSI) on a grid map. The locating process is a gradient-based motion control which refers to the RSSI measurement in the grid map. We simulated the locating algorithm in Matlab. The result of the simulation demonstrates a good locating result in a RSSI map without fading effect. In a RSSI map with Rayleigh fading, multiple movements and variations in step size are integrated into the algorithm to cope with measurement errors by the fading effect of the RSSI. | 41 pages
