In RFID systems, the reader identifies tags through communication over a shared wireless channel. When multiple tags transmit their IDs simultaneously, their signals collide, increasing the identification delay. Therefore, many previous anti-collision protocols, including an adaptive query splitting protocol (AQS) and an adaptive binary splitting protocol (ABS), focused on solving this problem. This paper proposes one blocking protocol, blocking ABS protocol (BA), based on ABS. BA not only inherits the essence of ABS which uses the information of recognized tags obtained from the last process oftag identification, but also adopts a blocking technique which prevents recognized tags from being collided by unrecognized tags. Finally, the simulation results show that BA outperforms ABS
