PROJECT TITLE :
An Effective Frame Breaking Policy for Dynamic Framed Slotted Aloha in RFID
The tag collision problem is considered as one of the critical issues in RFID system. To further improve the identification potency of an UHF RFID system, a frame breaking policy is proposed with dynamic framed slotted aloha algorithm. Specifically, the reader makes effective use of idle, successful, and collision statistics during the first observation part to recursively determine the optimal frame size. Then the collided tags in each slot can be resolved by individual frames. Simulation results show that the proposed algorithm achieves a better identification performance compared with the prevailing Aloha-based algorithms.
