Abstract :
Nowadays, the radio frequency identification (RFID) system is widely used in smart cards and tracking pallets. RFID is an automatic identification system which consists of two main components - tag and reader. RFID reader uses a multiple access scheme - the anti-collision protocol to identify multiple tags. Anti-collision protocol in RFID system has been investigated by many papers in the past. Chen and Lin propose an estimation model based on the empty time slots, and Cha and Kim estimate the number of tags based on the collided time slots for the frame-slotted ALOHA (FSA) anti-collision protocol. In this paper, the capture probability is first studied and incorporated into the FSA to evaluate how much throughput can be achieved mathematically with capture. Then, a different method to investigate the capture effect in the advanced design system (ADS) simulation environment is proposed.
