Abstract
In the high-density deployment scenario of the next generation wireless local area network (WLAN), the intensification of conflict makes spectrum utilization low. In order to improve the spectrum efficiency, the academia and industry will introduce Co-frequency Co-time Full Duplex (CCFD) technology into MAC as a key technology. However, the existing full-duplex Medium Access Control (MAC) protocol based on access point (AP) scheduling has the problem of low success rate in establishing full-duplex links. In order to solve this problem, a dynamic full-duplex link matching algorithm based on Binary-Graph is proposed, which is based on the author’s earlier research on FD-OMAX [16]. This algorithm uses bipartite graph to establish the relationship model between full-duplex link and Resource Unit (RU). In each round of full-duplex transmission, AP establishes the optimal full-duplex link transmission based on the user’s dynamic interference information on RU resources. In order to improve the success probability of establishing full-duplex links and spectrum efficiency, an enhanced trigger-free full-duplex MAC protocol, EnFD-OMAX, is designed on the basis of FD-OMAX protocol. The simulation results show that compared with FD-OMAX protocol, MuFuPlex protocol, OMAX protocol and FuPlex protocol, the throughput distribution of EnFD-OMAX protocol increases by 26.5%, 56.60%, 88.37% and 118.4% under saturated traffic. In high-density deployment scenarios, the probability of full duplex link to successful transmission and MAC efficiency are increased by 88.98% and 149.9% respectively compared with OMAX protocol.
