摘要
针对当前无线传感网质心定位算法的不足,提出了一种基于已定位节点辅助下的改进质心定位方法。通过独立定位计算与综合定位分析,最终获得精确的位置信息。本方法同时扩展了网络中可定位节点的范围,从而使得全网内的节点都可以方便地进行定位。
Aim at some defects of the centroid localization algorithm in current wireless sensor network,a type of improvement centroid localization method with the help of auxiliary beacon nodes which is original the unknown nodes is proposed in this paper.By independent localization calculation and integrated localization analysis,the accuracy of location is improved.This kind of means also extend the domain of wireless sensor network node which can be located easily.
