摘　　要：为提高无线传感器网络的生存周期,提出一种基于能耗均衡和分区优化的LEACH路由协议改进算法。根据节点与汇聚节点间的距离进行分区,不同分区内的传感器节点采用不同的簇头选举阈值公式,通过引入距离因子和剩余能量因子改进簇头选举的阈值公式。仿真结果表明,无论汇聚节点是在传感器节点的部署区域还是远离部署区域,改进后的算法可有效减少无线传感器网络能量消耗,延长网络的生命周期。To prolong the survival time of wireless sensor networks,an improved LEACH routing protocol based on energy balance and partition optimization was presented.Different partitions were divided according to the distance between nodes and sink nodes,sensor nodes in different regions adopted different clustering head election threshold formula,and the threshold formula of cluster head election was improved by introducing distance factor and residual energy factor.The simulation results show that the improved algorithm can effectively reduce the energy consumption of the wireless sensor network and prolong the life cycle of the network,regardless of whether the aggregation node is in or away from the deployment area of the sensor node.
