摘　　要：为提高经典LEACH路由协议的功能表现,解决因选取过程中簇头节点过于集中带来的相关问题,对LEACH协议中簇首的选取以及簇首到基站的通信进行优化。从原理上详细分析LEACH的算法原理,并在此基础上提出改进的LEACH路由算法。改进算法在簇首选取过程中考虑节点的剩余能量和空间位置,在数据稳定传输阶段采用多跳方式传递数据。通过MATLAB进行仿真实验,结果显示改进后的LEACH算法有助于减少节点的能量消耗,延长了网络节点的生命周期。In order to improve the performance of classic LEACH routing protocol and solve the related problems caused by too concentrated cluster head nodes in the selection process,the selection of cluster head and the communication between cluster head and base station in LEACH protocol are optimized.The algorithm principle of LEACH is analyzed in detail in principle,and an improved LEACH routing algorithm is proposed on the basis.The improved algorithm considers the residual energy and spatial position of nodes in the process of cluster selection,and transmits data in multi-hop mode in the stable data transmission stage.The simulation experiment by MATLAB shows that the improved LEACH algorithm is helpful to reduce the energy consumption of nodes and prolong the life cycle of network nodes.
