RIL — reliable RFID based indoor localization for pedestrians

Various approaches based on different wireless technologies have been proposed for indoor localization; however RFID technology remained the key focus of research in recent years compared to other technologies available on the market. RFID localization solutions are based either on tag detection count or signal attenuation, yet their reliability are not consistent. In this paper, we propose a novel approach that guarantees a reliable solution for indoor localization. Our localization algorithm confines the userpsilas location by a combination of tag detection and RSSI measurement. The results are refined by the use of filtering algorithm.
