| 摘 要： | 机场停机坪内特种车辆的定位是机场场面监控的重要部分,基于无线传感器网络实现对机场特种车辆的实时定位。针对RSSI值易受环境影响问题,采用高斯模型对采集的RSSI值进行筛选,通过空间补偿模型将节点映射到同一平面,并提出了修正加权质心定位算法,修正权重系数,提高定位精度。仿真结果表明,该算法能够满足机场特种车定位精度的要求。

| Abstract: | The localization of airport special vehicles is an important portion of airport surface monitor on the airport apron.The paper realized the real-time localization of the airport special vehicles on WSN.Arming at environment influence problem of RSSI,Gaussian model was applied to choice RSSI values.A space compensating model makes all nodes in a flat surface.A modified weighted cancroids localization algorithm improves the precision of localization.The simulation result show the modified weighted cancroids localization algorithm has met the requirements of the airport special vehicles localization accuracy. |
