一种提高网络寿命与节点定位性能的WSNs分群算法
New clustering algorithm for improving network lifetime and location accuracy in WSNs
摘要
Abstract
According to the nodes deployed randomly in the large scale wireless sensor networks,this paper proposed a new clustering algorithm to prolong the network lifetime and improve the location accuracy.The algorithm selected the optimal node set based on the discrete particle swarm optimization algorithm by trading off the networks energy consumption,the energy load balance and the location accuracy.Furthermore,the selected node sets were grouped into cluster for further location.The sim-ulation analysis was carried out under the RSSI/TDOA two rounds cooperative location scheme.Simulation results show that this algorithm guarantees the member nodes multi-hop communication in the cluster,improves the location accuracy and pro-longs the network lifetime.关键词
