摘要
Abstract
An advanced distributed localization algorithm based on MDS was proposed,which attempted to improve the node localization accuracy of the classical MDS-MAP algorithm in wireless sensor network. During the course of producing local node distance matrix,a new distance estimates method from Euclidean localization algorithm is intro-duced. Besides,a more effective transforming technology which based on the least-squares approximation is used to replace the original one, to transform the relative coordinate system to absolute coordinate system. Experimental results show that in the same experiment environment, compared with the classical MDS-MAP algorithm, the improved algorithm is more reliable in various topology networks.关键词
