【摘要】 主要关注利用Crossbow公司开发的Stargate网关做双层网络中的领导节点层的应用程序开发.基于到达时间偏差(Time Difference Of Arrival,TDOA)的定位技术对于传感器网络应用的有效性有着关键的作用.本文主要利用节点已采集的测距数据,在Stargate上应用拉依达准则剔除粗大误差并实现基于中值绝对偏差的滤波程序开发.最后在PC机上运用Matlab分析滤波的效果如何,以及分析产生误差的原因.更多还原

【Abstract】 This paper mainly concerns the Stargate,which is development by the Crossbow company,doing Gateway’s leading network layer application development.Localization technology,based on the arrival time deviation(Time Difference Of Arrival.TDOA) is crucial to the effectiveness of sensor network applications.We remove the gross errors according to the Pauta criteria and do data processing based on the value of the absolute deviation filtering algorithm on Stargate.Finally,we analyze the effectiveness of filtering with Matlab on PC,and do error analysis.更多还原
