基于协同预测的无线传感器网络全移动节点定位算法
Moving node localization algorithm based on cooperated prediction for wireless sensor networks
摘要
Abstract
The node localization technology is one of the key issues in wireless sensor networks.This paper analyzed the radio path loss model,established a fitting model between RSSI and distance,proposed moving node localization algorithm based on cooperated prediction.The algorithm solved the problem that the unknown nodes couldn’t be located when the number of an-chor nodes were less than three.The historical location coordinated of unknown nodes were used as the location of virtual an-chor node.The moving speed was used as the virtual communication radius.Simulation results show that,compared with the traditional RSSI localization algorithm,the proposed algorithm’s success rate of unknown node localization is improved by a-bout 30% and the average relative error is reduced by about 47%.关键词
