Research into Tag Anti-collision Algorithms in RFID

Tag anti- collision is one of the key problems of RFID System. The technique of TDMA can solve this problem. In TDMA, there are several anti- collision algorithms, such as ALOHA, Slotted ALOHA, binary search, dynamic binary search, etc. These algo- rithms are different in realization mode and application efficiency. This paper provides analysis and argumentation of them.
