Ray tracing-based radio propagation modeling for indoor localization purposes

This paper regards the application of ray tracing (RT) tools for indoor localization techniques. The paper presents two possible applications of RT tools in that context. The first is the train/construction of fingerprints databases in order to complement or/and replace laborious measurement campaigns. The second application is the modeling of location-dependent parameters in order to feed localization techniques. These two applications are investigated and validated using three RT tools applied on a synthetic indoor environment. The obtained results showed that RT tools are reliable in both fingerprinting databases construction and LDPs modeling.
