基于优化成簇多跳的 LEACH 协议改进
IMPROVING LEACH PROTOCOL BASED ON OPTIMISED CLUSTERING AND MULTI-HOP ROUTING
摘要
Abstract
In light of the problems of coverage holes and energy holes of cluster-based routing protocol in wireless sensor networks (WSNs) caused by uneven energy consumption within the cluster heads and inter-cluster,the paper proposes an improved LEACH protocol based on optimised clustering routing.According to energy consumption model of communication radio frequency,when clustering it adopts the modes of partition optimisation and dual-cluster heads to avoid the “coverage hole”problem brought in by uneven distribution in clustering space and cluster heads;When inter-cluster routing it selects the route with least cost based on cluster heads energy and the distance to the base station, thus makes up the “energy hole”phenomenon led by uneven energy consumption of cluster heads.The improvement has been tested by simulation experiment,and results show that compared with LEACH and the similar improved algorithms,this one effectively reduces the energy consumption of network and prolongs WSNs lifetime,meanwhile it enhances the data throughput of networks as well.关键词
