摘　　要：针对无线传感器网络簇头节点负载不均衡的问题,提出一种基于负载均衡的簇间路由协议。该协议通过记录邻居簇头节点到Sink节点的最小跳数信息建立到Sink节点的多条路径,根据簇节点的剩余能量和负载选择合适的路径进行路由,从而实现了簇头节点间的负载均衡。仿真实验结果表明,该路由协议能有效地均衡网络负载和簇头节点能量消耗,减少数据传输延迟,延长网络生存时间。A load balancing inter-cluster routing （LBC） protocol in wireless sensor networks was proposed to balance cluster head load. Based on the minimum hops to sink node, multiple paths were built from cluster heads to the sink node. And the routing strategy took the residual energy and load into consideration, thus load balancing between cluster heads could be achieved. Simulation results show LBC can effectively balance the load and energy consumption of cluster heads, decrease the delay of packets, and obviously prolong the lifetime of networks.
