摘要

Modern infrastructure, such as dense urban areas and underground tunnels, can effectivelyblock all GPS signals, which implies that effective position triangulation will not be achieved.The main problem that is addressed in this project is the design and implementation of an accuratevehicle location system using radio-frequency identification (RFID) technology in combination withGPS and the Global system for Mobile communication (GSM) technology, in order to provide asolution to the limitation discussed above. In essence, autonomous vehicle tracking will be facilitatedwith the use of RFID technology where GPS signals are non-existent. The design of the system and theresults are reflected in this paper. An extensive literature study was done on the field known as theInternet of Things, as well as various topics that covered the integration of independent technologyin order to address a specific challenge. The proposed system is then designed and implemented.An RFID transponder was successfully designed and a read range of approximately 31 cm wasobtained in the low frequency communication range (125 kHz to 134 kHz). The proposed system wasdesigned, implemented, and field tested and it was found that a vehicle could be accurately locatedand tracked. It is also found that the antenna size of both the RFID reader unit and RFID transponderplays a critical role in the maximum communication range that can be achieved.
