An Energy-Saving Anti-Collision Algorithm for the Active RFID Systems by Decreasing the Overhearing Slots

Article Preview

Abstract:

Anti-collision algorithms for active RFID system which are based on the ALOHA always have a serious overhearing problem because of the random selection in the system. Although the active tag can avoid the overhearing problem to some extent by applying the tree-based deterministic anti-collision algorithm, the system will using more time on account of more reader queries. We propose a novel algorithm which based on the superiorities in the recalled protocols. Simulation results show that the algorithm effectively reduce excessive inventory listening and system delay.
