Abstract
Recently RFID systems have become a very attractive solution for a supply chain and distribution industry to trace a position or delivery status of goods. RFID has many advantages over barcode and vision recognition systems, but there are still many problems to be solved. One of the important issues is channel efficiency. To get higher efficiency, a reader uses an anti-collision algorithm. In this paper, we characterize a set of anti-collision algorithms based on a framed slotted ALOHA protocol when using EPC-C1 Gen2 protocol with different frame sizes. Additionally, we propose a simple and effective algorithm which called DDFSA. The proposed algorithm outperformed a conventional Dynamic Framed Slotted ALOHA with a threshold method by 14.6% on average. We also explain why Gen2 has a good channel efficiency in bad environment.
