Knowledge of positions of sensor nodes in Wireless Sensor Networks (WSNs) will make possible many applications such as asset monitoring, object tracking and routing. In WSNs, the errors may happen in the measurement of distances and angles between pairs of nodes in WSN and these errors will be propagated to different nodes, the estimation of positions of sensor nodes can be difficult and have huge errors. In this paper, we will propose localization algorithm based on both distance and angle to landmark. So, we introduce a method of incident angle to landmark and the algorithm to exchange physical data such as distances and incident angles and update the position of a node by utilizing multiple landmarks and multiple paths to landmarks.

Ad-Hoc传感器网络的基于AOA的定位算法

了解无线传感器网络（WSN）中传感器节点的位置将使许多应用成为可能，例如资产监视，对象跟踪和路由。在无线传感器网络中，在无线传感器网络中的节点对之间的距离和角度的测量中可能会发生误差，并且这些误差将传播到不同的节点，传感器节点的位置估计可能很困难并且具有巨大的误差。在本文中，我们将提出基于距离和角度到地标的定位算法。因此，我们介绍了一种向地标入射角的方法以及一种算法，该算法可交换距离和入射角之类的物理数据，并利用多个地标和通往地标的多个路径来更新节点的位置。
