In this paper, localization error of the received signal strength (RSS)-based method in mixed
LOS/NLOS conditions is analysed. In contrast to the time of arrival, time-difference of arrival
and angle of arrival, RSS measurements are low-cost and ubiquitous in the indoor
environment. The localization inaccuracy for the RSS-based method is first computed in the
presence of NLOS positive bias using perturbation analysis. Subsequently, root-mean-
square localization error is determined using Cramér–Rao lower bound analysis under the …

Abstract
In this paper, localization error of the received signal strength (RSS)-based method in mixed LOS/NLOS conditions is analysed. In contrast to the time of arrival, time-difference of arrival and angle of arrival, RSS measurements are low-cost and ubiquitous in the indoor environment. The localization inaccuracy for the RSS-based method is first computed in the presence of NLOS positive bias using perturbation analysis. Subsequently, root-mean-square localization error is determined using Cramér–Rao lower bound analysis under the range error. Experimental results for mobile phone localization in two different indoor environments are shown to attain theoretical bound asymptotically.
