摘　　要：采用分布式模糊控制器方法,对无线传感器网络进行容错非均匀分簇.首先将节点剩余能量、节点中心度以及节点到基站的距离输入模糊控制器,通过IF-THEN规则进行推理,输出"成为簇头机会"和"簇大小"值,使性能最优节点成为簇头并组建大小合适的簇;其次,采用时分复用方式进行数据传输,可容忍簇头和成员节点的临时和永久故障.仿真结果表明,该算法能有效均衡簇间负载,降低网络能耗,从而提高了网络的生命周期.We used a distributed fuzzy controller method to carry out the fault tolerance and non-uniform clustering for wireless sensor networks.First,the residual energy of nodes,centrality of nodes and distance from nodes to base station were input to the fuzzy controller.The IF-THEN rule was used to reason and output＂cluster head opportunity＂and ＂cluster size＂value to make the best performance node become cluster head and build a suitable cluster size.And then data transmission by time division multiplexing mode could tolerate the temporary and permanent faults of the cluster heads and member nodes.The simulation results show that the algorithm can effectively balance the load among clusters,reduce the energy consumption of the network,and thus improve life cycle of the network.
