Abstract

Abstract

Full duplex communication technology can improve the link capacity and spectrum utilization, which brings great changes to the existing Wireless Local Area Network (WLAN). To Solve the compatibility issues in the process of half-duplex WLAN evolution to full-duplex WLAN, a HYbrid-Duplex MAC protocol (HYD-MAC) is proposed. According to the application scenarios and the full-duplex capability of the stations, the Request To Send/Clear To Send (RTS/CTS) frames are expanded and HYD-MAC can adaptively choose one from the four duplex modes, which are the synchronous full duplex, the asynchronous full duplex, the conditional half-duplex and half-duplex. The link establishment process of HYD-MAC protocol in four transmission modes are presented, and the network performance such as the network saturation throughput and medium access delay of the proposed protocol are analyzed. The results show that the HYD-MAC protocol can satisfy the communication requirements of the full-duplex network, half-duplex network and hybrid-duplex network at the same time by sacrificing little throughput and delay performance.
