An Enhanced Slotted ALOHA Algorithm for Anti-collision in RFID System

The anti-collision algorithm is one of the key problems in the RFID application system and the Time Division Multiple Access (TDMA) technique can be adopted to solve this problem; its relevant methods involve such anti-collision methods as ALOHA mehod, slotted ALOHA method, binary search, dynamic binary search, and so on. This paper mainly involves the study on the technology of multi-tag anti-collision that is key in RFID system, with a view to optimizing the anti-collision technology now available and enabling the identification of multi-tag technology more efficient to a certain extent.
