An Anti-collision Algorithm Using Two-Functioned Estimation for RFID Tags

Radio Frequency Identification (RFID) has recently played an important role in ubiquitous sensing technology. While more advanced applications have been equipped with RFID devices, sensing multiple passive tags simultaneously becomes especially important. In this paper, using complementarily two-functioned estimation, we propose an identification method based on the stochastic process. The underlying mathematical principles and parameters estimation models have also been well discussed. Numerical examples are given to verify the proposed two-functioned estimation identification method within a given expected accuracy-level. Key Words: RFID (Radio Frequency Identification), Anti-collision Algorithm, Two-functioned Estimation.
