Abstract: In the RFID system, one of the problems that we must solve is the collision between tags which is a key technique of the RFID system. An anti-collision algorithm for RFID systems based on tag grouping is put forward. The proposed algorithm compared to conventional ones, when there are a large number of tags in the field, can achieve high system efficiency by restricting the number of unread tags. Simulation results show that the proposed algorithm improves the slot efficiency above 80% at least compared to the conventional algorithms when the number of tags reach 1,000.

Keywords: radio frequency identification; RFID; anti-collision algorithm; tag grouping; adaptive frame slotted.
