Wireless full-duplexing enables a transmission and a reception on the same frequency channel at the same time, and has the potential to improve the end-to-end throughput of wireless multi-hop networks. In the present paper, we propose a media access control (MAC) protocol for wireless full-duplex and multi-hop networks called Relay Full-Duplex MAC (RFD-MAC). The RFD-MAC is an asynchronous full-duplex MAC protocol, which consists of a primary transmission and a secondary transmission. The RFD-MAC increases the full-duplex links by overhearing frames, which include 1-bit information concerning the existence of a successive frame, and selecting a secondary transmission node using the gathered information. The gathered information is also used to avoid a collision between the primary and secondary transmission. Simulation results reveal that the proposed RFD-MAC improves up to 68%, 49% and 56% of end-to-end throughput compared to CSMA/CA, FD-MAC and MFD-MAC, respectively.

In this paper, we propose a routing protocol for directional full-duplex wireless (D-FDW) to reduce hidden terminal problems in multi-hop networks. The proposed routing protocol is an on-demand detour routing protocol, which reduces number of cross points among traffic flows. In general, the throughput of a detour route degrades excessively due to increase of the number of hops between source and destination nodes. However, D-FDW has a remarkable benefit that throughput does not degrade excessively as the number of hops between source and destination nodes becomes large. Thus, the proposed detour routing can bring out the potential of D-FDW effectively. We evaluate the performance of the proposed routing protocol via ns-3 computer simulations, and show that the proposed routing protocol can reduce hidden terminal problems and improve endto-end throughput performance up to 86.4% compared with the conventional AODV in a grid multi-hop network. To the best of our knowledge, this is the first routing protocol for D-FDW.

“…The MAC scheme proposed in [16] deals with contention resolution techniques to handle inter-node interference in FD networks. Other works propose solutions able to enhance the end-to-end performance in multi-hop FD networks, e.g., [17], where the use of directional antennas is addressed, [18], where frequency reuse to enhance outage probability is investigated, and [19], that proposes synchronous channel access. Finally, cross-layer approaches have been proposed, in which PHY layer techniques, such as node signatures [20] and attachment coding [2], are exploited to schedule transmissions in FD MAC schemes.…”

Abstract-In the last years, the advancements in signal processing and integrated circuits technology allowed several research groups to develop working prototypes of in-band full-duplex wireless systems. The introduction of such a revolutionary concept is promising in terms of increasing network performance, but at the same time poses several new challenges, especially at the MAC layer. Consequently, innovative channel access strategies are needed to exploit the opportunities provided by full-duplex while dealing with the increased complexity derived from its adoption. In this direction, this paper proposes RTS/CTS in the Frequency Domain (RCFD), a MAC layer scheme for full-duplex ad hoc wireless networks, based on the idea of time-frequency channel contention. According to this approach, different OFDM subcarriers are used to coordinate how nodes access the shared medium. The proposed scheme leads to efficient transmission scheduling with the result of avoiding collisions and exploiting full-duplex opportunities. The considerable performance improvements with respect to standard and state-of-the-art MAC protocols for wireless networks are highlighted through both theoretical analysis and network simulations.
