RSS Based Localization in presence of Uncertainties

This paper studies the received signal strength-based localization problem subject to reference node uncertainties.Using linearization technique, a least squares based algorithm is derived first and then considering the uncertainties as perturbation, a technique based on total least squares is proposed that has a closed-form solution. Simulation results confirm that the proposed technique outperforms the statof- the art algorithms.
