Abstract

This paper reports preliminary work with an RFID based real time location system (RTLS) designed for location and guidance of people in welfare facilities like the sanatorium which has the both of indoor and out door environment. The system consists of a number of fixed RF readers and a number of active RFID tags carried by the target object, or senior people. We compare the performance of several RTLS schemes which use the received signal strength indication (RSSI) values emitted by the moving active RFID tags. Traditional trilateration, fingerprinting, and well-known LANDMARC approaches are evaluated and compared using the SystemC-based computer simulation. Results show a mean estimated error (MEE) performance of 3m with the 130 tags according to the position updated frequency in our simulation environment.
