摘　　要：针对撒布型无线传感器网络提出了基于非度量多维标度的NMDS-MAP算法及NMDS-MAP(P)算法,两种方法采用TDOA等测距技术测量节点间距,利用非度量多维标度技术对未知节点进行定位,前者是集中式算法,后者是分布式算法。理论分析与仿真实验表明,两种算法具有较高的定位精度与健壮性。Two non-metric muhidimensional scaling based node localization algorithms are proposed for bestrewn wireless sensor networks,NMDS-MAP and NMDS-MAP（P）.They measure the pairwise distances between nodes with TDOA or other techniques, make use of non-metric multidimensional scaling technique to estimate the nodes location.The former algorithm is centralized,and the later distributed.Simulation experimentation demonstrates that the algorithms are more accurate and robust in positioning sensors.
