摘要

定位技术是无线传感器网络的关键技术之一。在对DV-Hop算法深入分析的基础上

提出了一种改进的CBDV-Hop算法。该算法引入了共线度的概念

通过对共线度设置阈值

从而挑选出传感器网络中质量高的信标节点进行位置估计。理论分析和仿真实验证明:该算法可以显著提高定位精度。

Abstract

Localization technology is one of the key technologies in wireless sensor networks（WSNs）.On the basis of analysis of the DV-Hop algorithm

an improved algorithm CBDV-Hop is brought out.The concept of collinearity is introduced into the algorithm.The algorithm sets a threshold of collinearity

and selects the high quality beacon node to estimate the position.Theoretical analysis and simulations experiment show that the algorithm can improve the localization precision.
