摘要： 针对分簇的无线传感器网络(WSN)中负载不均衡问题，提出一种实现节点负载均衡的WSN非均匀分簇算法。引入非均匀簇机制计算出最优的网络分簇数量，通过调整节点的簇首归属来控制网络的分簇的大小，形成合理的网络拓扑结构。仿真实验结果证明，该算法能有效均衡网络的节点负载，降低节点能耗，延长网络的生存时间。

Abstract: Aiming at the load uneven problem in clustering Wireless Sensor Network(WSN), this paper presents an uneven clustering algorithm for achieving load balancing in WSN. The algorithm computes optimal network cluster numbers based on the uneven cluster, and adjusts the ownership of the node to form an appropriate architecture of the network topology. Simulation experimental results show that the algorithm can effectively balance the load of nodes, reduce the energy consumption and prolong the network lifetime.
