一种改进的无线粮情监测系统路由算法
An improved routing algorithm of granary wireless monitoring system
摘要
Abstract
Aiming at the characteristics of granary wireless sensor network,we propose an improved LEACH-based routing algorithm called EBHCR.EBHCR adopts centralized cluster-head election algorithm,and cluster member nodes use the single-hop to communicate with cluster-head.The distance threshold is specified for every cluster-head to determine the single-hop or multi-hop used between the cluster-head and BS(Base-station).The path weight of relay node adopts the node's remaining energy level and the optimal distances between relay node and the BS.Simulation results demonstrate that when the first death node appears,the EBHCR runs 135 rounds more than the LEACH; when 70％of the nodes died,the EBHCR runs 262 rounds more than the LEACH.The EBHCR's effective lifetime is 124.9％of the effective lifetime of the LEACH.The EBHCR algorithm is obviously superior to the LEACH in the energy balance,survival nodes and the effective lifetime of the wireless sensor network.关键词
