一种改进的基于DV-HOP的无线传感器网络定位算法
n improved localization algorithm based on DV-HOP for wireless sensor network
本文把协作思想融入DV-Hop定位算法,提出了一种改进的DV-Hop算法,改进算法在原始DV-Hop算法的基础上引入了迭代协作技术,改进了原始DV-Hop定位算法中计算未知节点平均每跳距离的方法并制定了选择锚节点三角形的规则。仿真实验结果表明,改进的DV-Hop定位算法大大改善了原始DV-Hop定位算法的定位性能,具有更高的定位精度和更广的定位范围,并且在锚节点数量比较小、节点密度低和传播半径小的情况下,仍具有较好的定位性能。
In this paper, cooperative theory is introduced into DV-Hop localization algorithm, an improved DV-Hop algorithm is positioned. On the basis of the traditional algorithm, the improved one inducts iterative cooperation theory, improves the computation method in the traditional algorithm of the average distance per hop and lay down the principle for choosing the anchor node triangle. A large number of simulation results demonstrate that the improved DV-Hop algorithm improves the localization performance of the traditional algorithm a lot with a higher localization precision and a wider localization scope, the improved algorithm keeps a good performance even with a small amount of anchor nodes, low density of nodes and a small transmission radius.
