本文研究了战术 WSN（无线传感器网络）的协作节点定位方案，该方案使用最少数量的锚节点提供准确的位置估计。应用一种高效的非线性数据降维技术——曲线分量分析（CCA），采用分布式地图生成算法来创建节点位置。所提出的使用 CCA 的新方法与另一种采用 MDS（多维缩放）非线性缩减方法的高效协作地图方案进行了比较，证明了位置估计精度和效率的提高。通过使用战术 WSN 部署场景的大量模拟实验，分析了这两种方案的优缺点。
This paper investigates a cooperative node localization scheme for a tactical WSN (Wireless Sensor Network) that delivers accurate location estimates using a minimum number of anchor nodes. An efficient non-linear data dimension reduction technique, the Curvilinear Component Analysis (CCA), is applied, adopting a distributed map generation algorithm to create the node locations. The proposed new approach using CCA is compared with another highly effective cooperative map scheme which employs the MDS (Multi-Dimensional Scaling) non-linear reduction method, demonstrating improved position estimate accuracy and efficiency. The strength and weakness of the two schemes are analyzed through extensive simulation experiments using tactical WSN deployment scenarios.
