Abstract
Recently, low-cost RFID tags have faced two serious problems. One is the performance decline occurred by collision and re-filter problem on readers. And the other is consumer privacy. The simultaneous and repeated responses of multiple tags give rise to collision and re-filter problem and seriously declines the recognition rate of tags. An efficient anti-collision protocol is needed to improve the recognition performance of low-cost RFID tags. In addition, security aspect has not to be overlooked. In this paper, we propose a scope-oriented anti-collision (SOAC) protocol in which a scope query is used to reduce collisions and passive tags with three states are designed to prohibit the repeated responses of recognized tags and bit-wise exclusive-OR operations are used to provide customer privacy during the communication. At the end, the performance of the proposed anti-collision protocol is analyzed.
