Abstract

This paper presents a quantitative comparison of various geolocation algorithms for the indoor wireless environment. Using models recently developed for time-of-arrival (TOA) distance measurement errors in the indoor environment, we characterize the performance of standard least-square (LS), closest-neighbor (CN), and the residual weighting (RWGH) algorithms in line-of-sight (LOS), obstructed LOS (OLOS), and mixed LOS/OLOS channel conditions. We also evaluate the performance of these algorithms in relation to the size of the indoor area over which a user is to be located.
