Abstract

The multi-robot system(MRS) is a structurally complex community. To realize the efficient cooperation of robots, information exchange-related problems must be first settled. Therefore, this paper proposed a multiple access control(MAC) protocol combined MRS with polling system in wireless local area network(WLAN). Firstly, this study probed into a point coordination function(PCF) access mechanism in this protocol, established a polling system model, applied the model into a centralized MRS architecture, and also analyzed its data transmission modes. Then, it derived expressions of the mean queue length, the mean latency and the mean polling cycle for information transmission in gate, exhaustive and limited robot(K=1) system. At last, it made a comparative analysis on the theoretical and simulation values of the above-mentioned three systems by virtue of MATLAB and ROS. As indicated by relevant results, the information transmission rate of MRS significantly increased with a rise in the arrival rate. Through comprehensive comparison of experimental results, the gate service system is superior to another two service strategies in elevating information processing speed and improving system performance on the premise of ensuring fairness. And in a context where the number of robots increases, the exhaustive service system, compared with the remaining two service strategies, performs best in information processing rates.
