一种基于能效优化的无线传感器网络改进LEACH路由方法
An improved LEACH routing method for wireless sensor networks based on energy efficiency optimization
摘要
Abstract
In order to address the problems of uneven energy consumption among cluster heads and prema-ture node failure in Low-Energy Adaptive Clustering Hierarchy(LEACH)routing for distributed wireless sensor networks(WSNs),this paper proposes an improved LEACH routing method based on threshold adjustment and in-ter-cluster routing,termed TC-LEACH.First,the method constrains the random numbers generated by nodes based on their energy levels,making low-energy nodes more likely to generate larger random numbers,thereby re-ducing their probability of being selected as cluster heads.Second,the cluster-head selection mechanism is opti-mized,and threshold parameters are adjusted to increase the probability of nodes with higher residual energy and closer proximity to the sink node.Finally,Dijkstra algorithm is used to optimize inter-cluster data transmission paths to minimize communication overhead.Simulation results demonstrate that the TC-LEACH algorithm reduc-es the overall energy consumption and prolongs the lifetime of the network by reducing network communication and balancing node energy consumption.关键词
