| 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。

| Abstract: | Two non-metric multidimensional 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. |
