摘　　要：为解决LEACH路由协议簇头选择算法的不足,针对在无线传感器网络选举簇头没有考虑节点的信赖值和簇内节点能量分布不均衡等问题,设计一种基于LEACH协议改进的新算法.通过计算节点的信赖值,作为选择新簇头节点的标准,最后对仿真试验进行性能分析比较,该算法能够满足生产需要,提高节点能量的效率,延长整个网络的生命周期,使网络均衡分配能量并且具有深远的意义.In order to solve the shortness of LEACH routing protocol cluster head selection algorithm,an improved protocol based on LEACH is proposed to solve the problems of node trust value and Energy dis-tribution imbalance. By calculating the trust value of the node,the new cluster head node is selected as standard. Finally,by the simulation analysis and comparison of performance,not only the algorithm can be used to meet the production needs and improve efficiency in the use of node energy,but also prolonge the network life cycle,The project figured out the problem that existed in balanced distribution of network en-ergy distribution with the wireless sensor.
