A Fast RFID Tag Anticollision Algorithm for Dynamic Arrival Scenarios Based on First-Come-First-Serve
Radio-frequency identification (RFID) tag anticollision algorithm is a key technology that affects the performance of RFID systems. In dynamic arrival scenarios, when the tags arrive the reader’s interrogation zone, they cannot participate in the ongoing identification immediately, resulting in longer waiting time and tag miss. Focusing on solving this problem, based on blocking technology, dynamic frame-slotted ALOHA (DFSA) algorithm, and the first-come-first-serve (FCFS) idea, a fast RFID tag anticollision...
