| 摘 要： | 针对无线传感器网络经典集中式多维定标MDS-MAP算法在定位精度与矩阵计算复杂度方面的不足,提出一种基于分布式的ADMDS-MAP定位算法.该算法通过采用测定距离量化,得到节点的近邻向量(CNV),然后通过相关的估算算法得到距离矩阵D和节点的初始估值,加入适当的求精计算得到节点的精确位置.理论分析和仿真实验表明,改进算法能够提高节点的定位精度.

| Abstract: | Aiming at the deficiencies of positioning accuracy and matrix operating complexity in the classical MDS-MAP locating algorithm in WSN, a distributed multi-dimensional scaling-MAP algorithm (ADMDS-MAP) was proposed in this paper. In this algorithm, the distance of the nodes was quantified to obtain the close-neighbor vector (CNV), the distance matrix D and the initial value of nodes location was calculated, and the locating accuracy was improved by refinement algorithm at last. Theoretical analysis and simulation experimental results show that, the advance algorithm can realize the positioning of sensor nodes with good accuracy. |
