Passive Radio Frequency Identification (RFID) network with several reader placed densely and close to each other are susceptible to reader collision problem. In this paper, a novel and efficient RFID reader�s anti-collision protocol is proposed based on Neighbor Friendly Reader Anti-collision (NFRA) mechanism by revising its contention procedure to provide higher throughput in dense reader network. The behavior of the algorithm is evaluated through a set of simulation experiments which demonstrates that the algorithm is 15 efficient than NFRA. It also has higher fairness as compared to NFRA and other state-of-the-art proposals. © Springer International Publishing Switzerland 2015.
