能耗均衡的低功耗自适应集分区路由改进算法

针对LEACH算法簇头选取不佳、网络寿命过短问题,提出一种基于分区的LEACH改进算法。该算法根据节点剩余能量、邻居节点数及距基站距离对簇头选举产生的影响,对簇头选举函数进行优化;对监测区域进行分区,不同分区采取不同的数据传输方式,减少基站附近簇头节点转发信息的负载量,有效避免基站附近“能量空洞”现象的发生。实验结果表明,相比于LEACH和LEACH-EDP算法,本文改进算法第一死亡节点出现轮次分别推迟了23.32%、18.44%,网络寿命分别延长了32.27%、21.49%。

Improved LEACH routing algorithm based on partitioning and energy consumption balance

Aiming at the problem of poor selection of LEACH algorithm cluster head and short network lifetime, an improved LEACH algorithm based on partition is proposed. The algorithm optimizes the cluster head election function according to the remaining energy of nodes, the number of neighbor nodes, and the distance from the base station on the cluster head election, and optimizes the cluster head election function; partitions the monitoring area, and uses different data transmission methods for different partitions to reduce cluster heads near the base station The load of the node forwarding information effectively avoids the occurrence of "energy holes" near the base station. The experimental results show that, compared with LEACH and LEACH-EDP algorithms, the first dead node of the improved algorithm in this paper is delayed by 23.32% and 18.44%, respectively, and the network life is extended by 32.27% and 21.49% respectively.
