多通信半径的无线传感器网络DV-Hop定位算法
Multi Communication Ranges DVHop Localization Algorithm for Wireless Sensor Network
摘要
Abstract
In order to realize high precision positioning of DV-Hop localization algorithm based on rang-free in wire⁃less sensor network,this paper improved the DV-Hop localization algorithm based on 2 or 3 communication radius, and improved the average per hop distance by the least mean square error criterion. The anchor node average per hop distance is repaired in the best index value. MATLAB simulation results show that the improved algorithm can improve the localization accuracy in randomly distributed environment,further enhance the localization accuracy in the best index,and greatly improve localization accuracy in the anchor node deploying artificial environment. The improved algorithm can achieve high precision positioning without increasing the number of flood and the cost in the network.关键词
