一种基于信标节点筛选的无线传感器网络定位算法
An Localization Algorithm Based on Selection of Beacon Nodes in Wireless Sensor Networks
摘要
Abstract
The locating algorithm of wireless sensor networks has been discussed in this paper. Some traditional locating algorithms are analyzed first,and then a novel Locating Algorithm based on Selection of Beacon Nodes(LASBN) is proposed. Proper beacon nodes can be selected in LASBN,and the weight of beacon nodes would be set according to RSSI received by unknown nodes. Finally,the coordinates of unknown nodes are evaluated by weighted centroid method. Theoretical analysis and experiments show that LASBN has polynomial complexity, can reduce the estimation error and improve the localization precision.关键词
