Empirical Study of Communication Connectivity Quality for Mobile Robots

For SWARM robots, the complicated tasks should be implemented by the cooperation among the individual robots. Due to the features of mobility and miniaturization, the perception and communication capabilities of such SWARM robots are usually limited. For the communication between the mobile robots, the transmission signal would suffer attenuation and disturbance in terms of the space-time factors in the process of wave propagation, and it could significantly affect the communication connectivity quality. In order to conquer this, the empirical study of the wireless communication connectivity between the mobile robots is presented in the paper, and a novel communication connectivity quality guarantee algorithm using RSSI feedback information and power control technique is proposed to improve the link-state quality. It relies the virtual force based on the RSSI measurement while utilizes an adaptive transmission power control scheme. The experimental results demonstrate the proposed algorithm is able to effectively conquer the effect from the time and space factors in a certain degree, and improve the connectivity quality of communication between mobile robots, and also achieve the energy efficiency.
