摘要
针对LEACH路由协议簇头选举问题,提出一种改进的路由协议LEACH_improve。如果簇头平均剩余能量小于阈值,则算法采用全网选举簇头方式。否则,依据节点剩余能量、距簇内质心的距离等约束条件算法使用簇内选取簇头方式。仿真结果表明:与经典路由协议LEACH相比,LEACH_improve提高了能量利用率,延长了网络生命。
Aiming at the problem of LEACH routing protocol cluster head election,the paper proposes an improved routing protocol LEACH_improve. If the average residual energy cluster head is less than the threshold value,the algorithm uses the whole network cluster head election mode. Otherwise,according to the residual energy,the distance from the cluster centroid and other constraints,the algorithm uses cluster internal election mode. The simulation result shows that,compared with the classical routing protocol LEACH,LEACH_improve improves the energy efficiency and prolongs the life of the network.
