Accelerating RFID Tag Identification Processes with Frame Size Constraint Relaxation

In the determination of suitable frame sizes associated with dynamic framed slotted Aloha used in radio frequency identification tag identification processes, the widely imposed constraint Q L 2 = often yields inappropriate values deviating far from the optimal values, while a straightforward use of the estimated optimal frame sizes causes frequent restarts of read procedures, both resulting in long identification delays. Taking a trade-off, in this paper, we propose a new method for determining effective frame sizes where the effective frame size changes in a multiple of a predetermined step size, namely Δ . Through computer simulations, we show that the proposed scheme works fairly well in terms of identification delay.
