Analysis of anti-collision protocols for RFID tag identification

Radio frequency identification (RFID) systems are becoming ubiquitous. Simultaneous transmissions in RFID systems lead to collisions as the readers and tags typically operate on the same channel. Therefore, anti-collision protocol is very important for solving the collision problem in RFID application system. This paper analyzes the primary anti-collision protocols for solving the collision problem in RFID tag identification, especially a novel and efficient anti-collision protocol, named collision tree protocol (CT), which stands for a new branch of tree-based anti-collision protocol for RFID tag identification.
