A Distributed Network Q-Mac with Quality of Service Provisioning

Wei SUN, Jin-ke HUANG

Abstract


A new distributed Cognitive Radio network Q-MAC has been proposed in the paper. The Q-MAC Protocol provides an efficient approach to address quality of service provisioning of delay sensitive applications. This MAC Protocol guarantees the QoS of network for such applications by giving priority to applications with higher time delay requirements in the stage of channel reservation. The performance of the Q-MAC Protocol with those of two existing protocols are compared. The results show that the Q-mac provides better throughput than those existing protocols. The analysis model and simulation results show that the designed Q-MAC Protocol is simple and effective. This Protocol can recognize and meet the QoS requirements of delay-sensitive applications and can effectively deal with the problem of multi-channel hidden terminal.
