    Abstract
  • A reader anti-collision algorithm based on random slot with a central computer coordination for radio frequency identification(RFID) systems was proposed. Firstly, the central computer sent the initial command and solt command, and the reader selected random slot based on utilization. If the reader which selected current slot didn-t receive busy signal of other readers, it sent beacon and listened. Then if the reader didn-t receive the beacon of other neighbour readers, it started to query tags. At the end of the slot, the reader which didn-t receive busy signal can sent second beacon. Compared to the existing distributed algorithm, the proposed algorithm had bettter throughput and fairness.
