THE ANTI-COLLISION ALGORITHM OF RFID BASE ON BREADTH-FIRST DYNAMIC BINARY SEARCH

摘要

The application of RFID in the ultra-high frequency band will become the mainstream of logistics industrial. For the RFID reader identifying a number of return signals from electronic tags under electromagnetic interference, achieving rapid and accurate information identification the most crucial factor is the anti-collision search algorithm. This paper studies dynamic binary search algorithm based on breadth-first, and optimizes the algorithm which improves the efficiency of radio frequency identification systems practically.
