Received Signal Strength-Based Robust Cooperative Localization With Dynamic Path Loss Model

Robust received signal strength (RSS)-based cooperative wireless localization using a linear least squares (LLS) method is proposed. We first extend the LLS methods to the cooperative case. To make the proposed algorithm robust, dynamic path loss models are utilized to describe the changing environm...

description	Robust received signal strength (RSS)-based cooperative wireless localization using a linear least squares (LLS) method is proposed. We first extend the LLS methods to the cooperative case. To make the proposed algorithm robust, dynamic path loss models are utilized to describe the changing environments; the path loss constants are updated based on the estimated positions of the client nodes. Furthermore, anchor nodes (reference nodes) calibration is considered to deal with the anchor node position errors. The simulation results are given for the proposed methods. Compared with the RSS-based non-cooperative LLS type methods, robust and better performance are obtained.
