Suffix-based double reader tag movement RFID anti-collision method

Abstract At present, some existing tag anti-collision algorithms are used mostly in scenarios of fixed number tags and they perform poorly moving scenarios. Therefore, this paper proposes a double reader movement RFID method based on suffix, through the cloud platform computing, supply chain data sharing is realized. Tag usually use single reader. The proposed employs to expand recognition range also prolong time, but there problem repeated recognition. This article suffix-based bit-slot ALOHA (SBSA) algorithm, where solved time-slot reduced. In view that large entering into area readers lead reduction efficiency. group (STGBSA) grouping estimation methods proposed. Complexity analysis deployed article, from perspective loss ratio identification efficiency, performances various evaluated compared with those methods. simulation results show better than
