Abstract: 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.
