| 摘 要： | 针对DV-Hop距算法定位误差大的难题,提出一种改进离估计误差,并利用DV-Hop的传感器节点定位算法。首先修正知节点与信标节DV-Hop算法对节点进行定位;然后对进V-Hop算法定位误差行校正,最后在Matlab 2012平台上对算法性能进行仿真分析。仿真结果表明,本文算法可以较好地克服DV-Hop算法存在的不足,提高了传感器节点的定位精度。

| Abstract: | In order to reduce localization error of the sensor node, a novel node localization algorithm is proposed in this paper based on improved DV-Hop algorithm. Firstly, estimation error of the distance between unknown and an_chor node is reduced and DV-Hop algorithm is used to obtain location of nodes; secondly, localization error of DV-Hop algorithm is corrected, finally, the simulation experiment is carried out to test the performance on matlab 2012. The results show that the proposed algorithm can correct the localization error of DV-Hop algorithm and significantly improve the location accuracy of wireless sensor network. |
