基于IMCB算法的无线传感器网络节点定位
Node Localization of Wireless Sensor Network Based on IMCB Algorithm
摘要
Abstract
Due to the problem of sample degeneration in Monte-Carlo Box(MCB) mobile localization algorithm, a new localization algorithm named Improved Monte-Carlo Boxed(IMCB) is proposed, which is applied to node localization of Wireless Sensor Network(WSN). Based on the MCB algorithm, through analyzing the localization results of current time, distance between nodes and the information of node relative position to obtain the sampling probability of different regional of sample box for next time, the sample points can fall in the area where the posterior probability is large as much as possible, therefore the problem of low accuracy caused by sample degeneration in MCB algorithm is solved effectively. Simulation results show that, under the same conditions, the average localization accuracy is improved by about 14%, and the average energy consumption for localization is reduced by about 17%by comparing with the MCB, MCL algorithm.关键词
