A new anti-collision algorithm based on RFID
2020
This paper first introduces some basic concepts of radio frequency identification(RFID), then introduces the RFID collision problem and the current popular anti-collision algorithm. Traditional anti-collision algorithms include ALOHA based anti-collision algorithm and binary tree based anti-collision algorithm. This paper mainly introduces ALOHA algorithm, slot ALOHA algorithm and dynamic frame slot ALOHA algorithm, compares the throughput parameters of each algorithm through calculation, and on this basis, proposes an improved dynamic frame slot ALOHA algorithm. This algorithm can achieve higher system utilization by dynamically changing the window size.
