(English Abstract)
In this paper, a QT_rev protocol is proposed for identifying all the tags within the identification range. The proposed QT_rev protocol revises the QT protocol, which has a memoryless property. In the QT_rev protocol, the tag will send the remaining bits of their identification codes when the query string matches the first bits of their identification codes. After the reader receives all the responses of the tags, it knows which bit is collided. If the collision occurs in the last bit, the reader can identify two tags simultaneously without further query. According to the simulation results, the QT_rev protocol outperforms the QT protocol in terms of the number of queries and the number of response bits.
