摘要
在分析了无线传感器网络的布局基本符合流形(manifold)特点的基础上,借助所提出的局部保持的典型相关分析(locality preserving canonical correlation analysis,简称LPCCA)进行建模,以建立从信号强度空间到现实物理空间的映射;进而提出了一种能够体现网络拓扑结构局部信息的无线传感器网络定位算法——LE-LPCCA(location estimation-locality preserving canonical correlation analysis).与现有同类算法在benchmark上的实验结果相比,LE-LPCCA具有更高的定位精度和稳定性.
