Abstract

This paper proposed FQMAC protocol used in the scenario of heterogeneous CRN coexisting. It divided time into beacon periods using beacon frame synchronization. During one beacon period, it performed respectively channel sensing, channel negotiation, and data transmission. It treated the channels occupied by secondary users of other heterogeneous networks as useful channels, too. It classified the useful channels into different levels according to their quality, and classified secondary users into different levels according to their service characteristics too. The high level users prioritized the high level channels. This paper obtained the reasonable duration of the channel negotiation phase by establishing a Markov chain model. Simulation results show that FQMAC can improve the throughput of the network, guarantee the users' QoS, and achieve better fairness.
