Abstract

In the RFID system, multiple tags respond in the process of identifying multiple tags in the reader's interrogation zone, resulting in collisions. Tag collision occurs when two or more tags respond to one reader, so that the reader cannot identify any tags. These collisions make it hard for the reader to identify all tags within the interrogation zone and delays the identifying time. In some cases, the reader cannot identify any tags. The reader needs the anti-collision algorithm which can quickly identify all the tags in the interrogation zone. The proposed algorithm efficiently divides tag groups through an efficient separation to respond, preventing collisions. Moreover, the proposed algorithm identifies tags without checking all the bits in the tags. The prediction with efficient separation reduces the number of the requests from the reader.

RFID 시스템에서, 리더의 인식영역에서 다수의 태그를 인식하는 과정에서 충돌이 발생하게 된다. 하나의 리더에게 두 개 또는 여러 태그가 응답하여 충돌이 발생하게 되며, 리더는 태그를 인식하지 못하는 일이 발생한다. 이런 충돌로 인해 리더는 인식영역 안에 있는 모든 태그를 인식하기 위한 시간이 길어지며, 이 경우 리더는 태그를 인식하지 못하는 경우가 발생된다. 리더는 인식영역 안의 모든 태그를 빠르게 인식할 수 있는 충돌 방지 알고리즘이 필요하다. 제안된 알고리즘은 태그의 응답을 효율적인 분리를 이용하여 태그 그룹으로 나누어 충돌을 회피한다. 또한, 제안된 알고리즘은 태그 아이디의 모든 비트를 알지 못해도 태그를 인식할 수 있다. 효율적인 분리를 통해 예측을 하여 리더로 부터의 응답 수를 줄인다.
