摘　　要：为了在无线传感器网络(WSN)中降低能耗和提高网络生存期,针对LEACH协议中簇头选举不合理和随机分簇的不足,提出了一种LEACH的改进协议。该协议首先计算无线传感器网络的最佳分簇数量,然后与遗传算法相结合对网络进行分簇,再根据簇中节点的剩余能量等情况选出簇头节点。仿真结果表明,与经典的LEACH协议相比,改进后的协议减少了网络的能量消耗,延长了网络生命周期。In order to reduce the energy consumption and prolong network lifetime in WSN（wireless sensor network）, an improved protocol based on LEACH（low-energy adaptive cluster hierarchy） is proposed to solove the problems of cluster-head nodes selection and random clustering. Firstly, the protocol ealeuaites the best clustering number in WSN, then integrates with genetic algorithm to cluster and chooses cluster-head nodes based on the nodes residual energy, Simulation results show that the improved protocol is much better than LEACH in en ergy consumption and lifetime.
