摘要
由于周围环境对无线传感器网络(WSNs)的影响,在布设到特殊环境下时会产生信号的衰减与损耗,导致通信不畅。针对此问题,提出一种以LEACH路由协议为基础适应特殊环境(长直空间)的新型路由算法。本算法采用链式传输,即从内部逐一将信号传输给距空间最外端且距基站位置较近的簇头,克服了内部节点死亡过快的问题。同时簇内采用链式传输并且改进簇头阈值与成簇半径,减小了能量消耗,提高了稳定性,克服了LEACH算法的不足。
Due to impact of surrounding environment on wireless sensor networks( WSNs),it will produce signal attenuation and loss in layout to special environment,resulting in poor communication.Aimed at the problem, propose a new routing algorithm based on LEACH routing protocol which adapts to special environment( long straight space).This algorithm uses chain transmission,it transmits the signal from the inside one by one to the cluster head that is in the outer side of the space and closer to the base station location,and overcomes problem of internal nodes dying too fast.Meanwhile,use chain transmission and improves the cluster head threshold and cluster radius in cluster,reduce energy consumption,improve stability,and overcome deficiencies of the LEACH algorithm.
