Code division cooperative identification reader anti-collision protocol in smart RFID systems

In this paper, an anti-collision protocol called code division cooperative identification protocol (CDCIP) is proposed in order to tackle the reader collision problem in smart RFID systems. CDCIP allocates orthogonal sequences to each reader and composes a RFID network. Consequently, it strives to let more than one reader work at the same time and at the same frequency. Eventually, comparing with the traditional protocol, the simulation results show that the proposed protocol offers better average throughput and lower power consumption of the system.
