Abstract
This paper proposes a protocol that considerably reduces RFID readers collision problems in a large-scale dynamic RFID system. HAMAC is based only on realistic assumptions that can be experimented and does not require any additional components on RFID reader in order to improve the performance in terms of throughput, fairness and coverage. The central idea of the HAMAC is for the RFID reader to use a WSN-like CSMA approach and to set its initial backoff counter to the maximum value that allows the system to mitigate collision. Then, according to the network congestion on physical channels the reader tries to dynamically control its contention window by on selected physical channel or after scanning all available physical channels. Extensive simulations are proposed to highlight the performance of HAMAC compared to literature’s work where both readers and tags are mobile. Simulation results show the effectiveness and robustness of the proposed anti-collision protocol in terms of network throughput, fairness and coverage.
