Abstract
In this paper, we introduce a framework termed Accelerated Frame Slotted Aloha (AFSA) for reducing the average reading time of passive RFID tags in dense environments. The proposed framework can be used in conjunction with almost all tag reading protocols that are based on frame slotted Aloha. AFSA reduces the tag reading time by decreasing the time wasted due to collisions and idle slots. We also discuss extensions of AFSA to read passive tags in a mobile setting. Simulation results show that AFSA can significantly reduce the average tag reading time with respect to the base protocol under both static and mobile settings.
