Abstract: A clustering algorithm for WSNs is proposed based on bayesian game.The algorithm Abstract cluster head election as a proceeding of multiplayer game and achieve a reasonable clustering distribution through the incomplete information among nodes.Since the design of payment function takes full account of node energy consumption, path loss and other factors, so the algorithm can achieve the reasonable distribution of cluster heads through game.Simulation results show that the algorithm can ensure energy consumption more stable under the real time of data transmission and make energy distribution more uniformly, prolong network lifetime effectively.
