Research on RFID tag anti-collision algorithm

Radio Frequency Identification (RFID) technology is a radio frequency signal using automatic target recognition and access to relevant information technology is now involved in all aspects of daily life. But it can lead to incorrect data reading because of collision. Tag anti-collision is one of the key problems of RFID system. The techniques of Time Division Multiple Access (TDMA) can solve this problem. There are several anti-collision algorithms, such as Aloha, Slotted Aloha, binary search, dynamic binary search and so on. We analysis and research various anti-collision algorithms and compare the differences between each other, and to obtain the most efficient algorithm. By comparing them, we can obtain the most efficient algorithms.
