摘要
本文在基于三维DV-Hop定位算法的基础上,提出了一种基于平均跳距修正的三维DV-Hop定位算法。该算法除了将DV-Hop定位算法从二维空间扩展到三维空间以外,还对未知节点到锚节点的平均每跳距离作了相应的修正,仿真结果表明:与原始算法相比改进后的算法定位精度有了一定提高。
This paper analyzing the three -dimensiona DV -Hop localization algorithm, and proposes an average hop correction three - dimensional DV - Hop localization algorithm, the new algorithm extended two -dimensional space to three -dimensional space, corrected the average hop distances between an unknown node and all anchor nodes. The simulation results show that in aspects of location accuracy, the new three - dimensional DV - Hop localization algorithm has great advantage over traditional algorithms.
