Comparative Performance Analysis of Empirical and Radio Propagation Model for Bluetooth Indoor Localization

Abstract--This work presents the possibility of using channel simulated results as alternative to site measurement for RSS based indoor localization. Three reference radio maps were generated for on-site measurement, Wall Attenuation factor (WAF) and Ray Tracer (RT) channel models. The Bayesian localization algorithm was applied to the three radio maps. An important performance metric called localization error was used which depends on the resolution of the reference radio map. Results obtained show that the performance of an RT model is comparable to a system based on on-site measurement for grid resolutions greater than 10 meters, on the other hand, the WAF model produced results that are very close to the on-site results for grid resolutions less than 8 meters
