An improved RFID anti-collision algorithm

摘要

The dynamic bit-locking backoff (DBLBO) anti-collision algorithm was proposed on the basis of bit-locking backoff (BLBO) anti-collision algorithm. If there is only one collision bit when the reader is searching the locked collision bit, the reader can identify directly without queries. The proposed algorithm gives full consideration to the number of queries and throughput of the system. The analysis on simulation result indicates that DBLBO performs significantly better than the existing BLBO anti-collision algorithms. It is suitable for the RFID anti-collision protocol in a greater deal.
