摘要
针对Cricket室内定位系统在没有获得足够的距离信息时无法对移动目标进行准确定位的问题,提出了一种基于时间序列分析ARMA模型的方法。在距离信息不足时根据移动目标历史位置信息构造ARMA模型,得到预测位置,再根据预测位置结合距离信息进行目标定位。实验结果表明,在传感器网络中,该方法在移动目标跟踪上是可行和有效的。
The Cricket Indoor Location System cant address the accurate position of moving targets when it has not sufficient distant information. In this paper, a method based on time series analysis ARMA model is proposed to solve this problem. It utilizes the historical position information to construct the ARMAmodel, and gets the predicted position. Then it uses the predicted position and distant information to get the accurate position. The simulation results show that the method is feasible and effective.
