Estimating the positions of sensor nodes is a fundamental and
crucial problem in ad hoc wireless sensor networks (WSNs).
In this paper, an accurate node localization method for WSNs
is devised based on the weighted least squares technique with

ISOMAP(Isometric Feature Mapping，等度规特征映射)算法在高维非线性数据处理中有较为理想的效果，建立在MDS (Multi-Dimensional Scaling，多维尺度变换)的基础上，其基本思想是当数据集的分布具有低维嵌入流形结构时，可以通过保距映射获得观测空间数据集在低维空间的表示。-ISOMAP (Isometric Feature Mapping, and other metric feature mapping) algorithm can get mo

Multidimensional Scaling(MDS)是一种经典的数据降维方法，同时也是数据可视化的一种手段。这个问题的最早起源，是当我们仅能获得物体之间的相似性矩阵时，如何由此来重构它们的欧几里德坐标。譬如，对一个国家的许多城市而言，假如我们并不能确定它们的经纬度信息，却知道所有城市两两之间的距离，就可以通过MDS方法将这些代表相似性的距离数据，呈现在二维坐标上。-Multidimensional Scaling (MDS) is a classical data dimensionali
