基于扇形分簇的无线传感器网络路由算法
Fan-shaped clustering based routing algorithm for wireless sensor network
摘要
Abstract
The low energy adaptive clustering hierarchy(LEACH)routing algorithm for wireless sensor network selects the cluster head node by means of equal probability,which is easy to result in the extreme energy loss of the whole network nodes, and reduce the network lifetime. Therefore,an improved LEACH algorithm for the selection and clustering of the cluster head node is proposed. The whole network area is divided into four fan-shaped subareas with the algorithm to perform the clustering routing in each subarea independently. The cluster head node of the base station is selected according to the node residual ener-gy and distance to the base station. The routing mode of the node is selected according to the cluster head node and the received signal strength of the base station to balance the network energy consumption. The simulation results show that the network life-time of the improved LEACH algorithm is 150% of the original LEACH algorithm,and its data throughout is increased by three times.关键词
