摘要

在无线传感器网络（WSNs）中

使用阵列天线进行到达角（AOA）估计存在成本昂贵和算法复杂度高的缺点

提出了一种基于接收信号强度指示（RSSI）的AOA估计算法。利用2个旋转的方向图部分重叠的定向天线接收RSSI值

通过双方向图求差法估计目标节点的AOA。实验结果表明:室内实验的AOA估计平均误差为6.7°

室外的平均误差为0.6°。该算法复杂度小

硬件成本低

适用于WSNs的节点定位。

Abstract

In wireless sensor networks（ WSNs）

because angle of arrival（ AOA） estimation algorithm using array antenna has disadvantage of high cost and high complexity

an AOA estimation algorithm based on received signal strength indication（ RSSI） is proposed. Using two directional antennas of rotating

directional pattern partial overlap to receive RSSI values and then AOA of target node can be estimated by using double directional pattern difference method. The experimental results demonstrate that the mean errors of AOA estimation for the indoor and outdoor are 6. 7° and 0. 6°

respectively. The proposed algorithm is of less complexity

low cost hardware and is suitable for node localization in WSNs.
