摘　　要：LEACH协议在簇头选举产生、能耗控制还存在许多问题,为此,对其产生方式提出改进。在原LEACH协议中加入网络中节点的具体位置信息和网络节点当前的剩余能量信息,在簇头选定阶段引入了备选簇头节点间距和模拟退火算法。在NS2上的仿真结果表明:改进的LEACH协议使簇头节点的选择更为合理,整个网络的寿命延长了50%,网络基站的接收数据量提高了175%。LEACH has many problems in election of cluster head and energy consumption control,aiming at these problems,propose improvement for generation mode of LEACH protocol cluster head. The improved LEACH protocol is to add specific location information of network nodes and current remaining energy information of network node in original LEACH protocol,alternative cluster head node spacing and simulated annealing algorithm are introduced in cluster head selection stage. The simulation results on NS2 show that the improved LEACH protocol makes selection of cluster head more reasonable,and the whole network lifetime is extended 50 %,and amount of receiving data of base station is increased by 175 %.
