| 摘 要： | 针对无线传感器网络（WSNs）节点的定位误差较大的问题,提出一种蝙蝠算法（BA）和DV-Hop算法融合（BADV-Hop）的定位算法.首先测量未知节点与锚节点之间的距离,然后采用DV-Hop算法初步确定未知节点的坐标,再采用BA校正DV-Hop算法的定位误差,最后在Matlab 2012平台上对算法性能进行仿真分析.实验结果表明：相对于DV-Hop算法,BADV-Hop算法提高了传感器的节点定位精度.

| Abstract: | Aiming at problem of big error of node localization of wireless sensor networks （ WSNs ）, propose a localization algorithm which is the fusion of bat algorithm （BA） and DV-Hop algorithm （BADV-Hop）. Firstly, distance between unknown node and anchor node is measured, and then the coordinate of unknown nodes is determined by using DV-Hop algorithm,then BA is used to correct localization error of DV-Hop algorithm, finally, simulation analysis is carried out on algorithm characteristics on Matlab 2012 platform. Results show that compared with DV-Hop algorithm, BADV-Hop algorithm can improve localization precision of node. |
