Abstract: In order to solve the problem of network performance balance, a polling control strategy of two queues was proposed, which was used for media access control of wireless sensor networks. First, in the polling control strategy, one queue took gated service and exhaustive service according to the probability of the total load rate of the system. The probability of taking the threshold service plus the probability of taking exhaustive service was equal to 1. Second, the control strategy model was systematically analyzed, and the model was described by the control flow method. Then, the simulation of the new control strategy model was realized by Matlab, and it was compared with the experimental results of the exhaustive service and threshold service under the same conditions. The experimental results showed that the control strategy can achieve the effect of balancing network performance. Finally, the existing MAC frame structure is analyzed, and the existing frame structure is redesigned to realize the rotation training strategy. The feasibility of the control strategy in the actual network is illustrated.
