In recent years, there has been considerable interest in indoor location-based applications such as asset management. While Radio Frequency Identification (RFID) technology has been designed for identification purposes, it can also be used for location tracking purposes. This paper presents an RFID-based location tracking system using a peer-to-peer (P2P) network architecture and investigates location estimation methods for the system. In summary, this paper makes three major contributions. First, the proposed system using a P2P architecture can facilitate system setup and management. Second, we investigate some position estimation methods using radio signal strength, reference tags, and a simple formula with dynamic parameters calibration for the positioning system. Third, we present experimental results, which give valuable insights into the design of an RFID-based position estimation system.
