A Pair-Resolution Blocking Algorithm on Adaptive Binary Splitting for RFID Tag Identification

For RFID tag identification, this research proposes a novel anti-collision method, the Pair-Resolution Blocking algorithm (PRB). It inherits the essence of a previous algorithm, the Adaptive Binary Splitting algorithm (ABS), and thus uses the information of recognized tags obtained from the last process of tag identification. Furthermore, PRB adopts a blocking technique which prevents recognized tags from being collided by unrecognized tags and utilizes a pair resolution technique which couples recognized tags to significantly reduce the identification delay. The analytical and simulation results show that PRB significantly outperforms ABS.
