摘　　要：针对无线传感器网络分簇路由协议中因簇间路由产生的簇头能量消耗不均衡的问题,提出一种簇头负载均衡的分簇算法。此算法在产生非均匀分布的簇头的基础上,建立由簇头组成的骨干传输网络的簇间转发路径,计算簇头的中转数据量。传感器节点在选择簇头时进一步考虑簇头的中转数据量,实现簇头的负载均衡。仿真实验结果表明,该路由协议有效地平衡了簇头的负载,并显著延长了网络的生存时间。Aimming at the problem of unbalanced energy consume of cluster heads caused by inter-cluster communications in wireless sensor networks clustering routing protocols,a novel algorithm named Cluster Head Load Balanced Clustering （CHLBC） is presented.Based on uneven distributed cluster heads,CHLBC builds backbone network＇s inter-cluster transit route which is composed of cluster heads and computes relay traffic of cluster heads.Sensors take the cluster head＇s relay traffic into consideration in the process of choosing the best cluster head and realize the load balance of cluster heads.Simulation results show that the routing protocol effectively balances the load among cluster heads and achieves an obvious improvement on the network lifetime.
