摘要： 定位技术是无线传感器网络中的关键支撑技术之一。针对移动无线传感器网络的特点，在深入分析现有多维定标节点定位算法的基础上，提出一种改进机制，即距离自调整的多维定标节点定位算法(SA_MDS)。该算法运用3种方法估算节点的两跳距离，然后自动调整节点间的估算距离，从而提高定位精度。仿真结果表明，采用SA_ MDS算法，节点的定位精度有较大提高。

Abstract: Localization is one of the key technologies in wireless sensor networks(WSNs). Considering the characteristics of WSNs, this work began with a thorough investigation of the existing MDS_MAP localization algorithm. On this basis,we proposed a self-adjusting distances localization algorithm(S人MDS). The basic idea behind S人MDS is to estimate the distance between the two-hop nodes with three approaches,followed by self-adjustment of the estimated dislances between nodes, in order to improve positioning accuracy. Our simulation results show that the SA-MDS algorithm improves the accuracy of node localization significantly.
Key words: WSNs, Localization, Multidimensional scaling, Distances of nodes
