A framework for fast RFID tag reading in static and mobile environments

A framework for reducing the average reading time of passive RFID tags in dense environments is introduced. The proposed framework termed Accelerated Frame Slotted ALOHA (AFSA) can be used in conjunction with almost all RFID tag reading protocols that are based on frame slotted ALOHA. It is shown that AFSA reduces the tag reading time by avoiding the wastage in bit times due to collisions and idle slots. The implementation of AFSA in conjunction with two different ALOHA protocols
