Distributed Angle Estimation for Wireless Sensor Network Localization With Multipath Fading
In this paper, the authors propose a distributed angle estimation method for wireless sensor network localization with multipath fading. The multiple antenna system is equipped at the anchor and the Angle Of Departure (AOD) can be estimated individually at each sensor node with single antenna system. Further, they exploit the space diversity to improve the estimation performance by deploying multiple parallel arrays at the anchor. Analysis and simulations demonstrate the effectiveness of their method. Wireless Sensor Networks (WSNs) localization is a significant technology attracting considerable research interest recently, wherein the angle estimation constitutes an important component of existing location systems.
