一种基于锚节点分簇的传感器网络节点定位方法
Node localization method based on anchor clustering in wireless sensor networks
摘要
Abstract
This paper proposed a method of nodes localization based on anchor clustering( I.AC) .improved the localization accuracy by using this method in the wireless sensor networks. All the nodes was divided into many clusters which anchor as a center autonomously and the fake anchor defined as the node located on margins of clusters. Built the distance matrix between the nodes by using measuring methods,obtained a local relative map of a cluster by using multi-dimensional scaling( MDS) algorithm and anchor positional information, implemented the global map by using of nodes positional coordinate transformation of anchor and fake anchor. Simulation results demonstrate that LAC is more robust to disturbance effect and higher accuracy performance in the nodes localization.关键词
