STUDIES ON TAG ANTI-COLLISION ALGORITHMS
RFID for containers has the advantages of small size, and it can be reused many times, and the data storageis big, and can be read easily, with quick dynamic scanning, and can deal with multi-target recognition, so it is massively used in logistics. With all the strengths mentioned, it still has the weakness of system visit conflicts. In a RFIDsystem of many readers and many tags, there are two conflicts: single reader--multi-tags conflicts and multi-readers--multi-tags conflicts. First, the way of tags emit RFID signals and different anti-conflicts algorithms are talkedabout in this paper, which are tree form algorithm, ALOHA algorithm, slotted ALOHA algorithm and ColorWave algorithm. And it analyzed each way in terms of dealing with conflicts. Then it compared the merits and faults of thesealgorithms. And finally it put forward a way to go in the field of anti-conflicts.
