A novel anti-collision scheme for RFID systems

Because of low cost and easy-to-use feature for RFID cards, more and more operators adopt RFID technique to identify their goods. When there are many goods with RFID cards put together, collision happens when trying to identify each good from the other. Some tree-based schemes are proposed to solve this problem. However, tree-based schemes have long identification time, and they need much data exchange. A novel anti-collision scheme for RFID systems is proposed in this paper. Theoretical analysis proves that the proposed scheme decreases the identification time as well as minimizing data exchange.
