在深入分析无线传感器网络路由协议设计目标的基础上,根据LEACH协议分层设计的思想,融入了负载平衡和簇内成树的思想,通过控制簇头之间的位置,使得簇的分布较为均匀,同时簇内节点根据节点的高度值形成一棵树,让节点采集到的数据沿着这棵树进行传输,使得簇内节点由单跳传输变成了多跳传输,很好的均衡了网络能耗。通过理论分析和仿真结果表明改进后的协议极大的延长了网络生命期,sink节点数据收集量也增加不少。 Based on the deep analysis of the design goals of WSN routing protocol, according to the idea of ​​hierarchical design of LEACH protocol, the idea of ​​load balancing and intra-cluster integration is incorporated. By controlling the position between cluster heads, the cluster distribution is more uniform At the same time, the nodes in a cluster form a tree according to the height of the nodes, so that the data collected by the nodes are transmitted along the tree, so that the nodes in the cluster become multi-hop transmission from single-hop transmission, which well balances the network Energy consumption. The theoretical analysis and simulation results show that the improved protocol greatly prolongs the network lifetime and the sink node data collection also increases a lot.
