%X In sparse sensor networks,most existing localization algorithms cannot work properly due to the lack of distance and connectivity information to uniquely localize sensors.A new nonmetric MDS mobile assisted 1ocation algorithm,NMDS-LRA(M),was presented to solve the problem.The algorithm samples the tracks of mobile nodes,and then computes the approximate matrix of dissimilarity matrix by use of singular value decomposition.In other algorithms,the high error of distance among virtue nodes deteriorate the loca...
