摘　　要：基于信号到达角度(AOA)的定位算法是一种常见的无线传感器网络节点自定位算法,算法通信开销低,定位精度较高。由于各种原因,估测的多个节点位置可能存在不可靠位置,提出了一种改进的基于信号到达角的定位方法,通过过滤误差较大的估计位置,来提高定位的精度。仿真结果表明,本文提出的改进算法很好地提高了定位精度。AOA is a typical way for the nodes self-localization in WSN.It can reduce the spending of communication and also achieve high location precision.For the estimated location,there maybe unreliable locations due to many reasons. An improved localization algorithm in wireless sensor networks based on angle of arrival is proposed. It can improve the location accuracy by filtering the unrelllable location. It is shown by the experiments that the improved algorithm proposed in this paper has high localization precision.
