Abstract:

Wireless full-duplexing enables multi-hop wireless networks to increase network performance, such as the end-to-end throughput. However, the combination of wireless full-duplexing and multi-hop communication produces a secondary transmission collision problem due to the increase of transmission opportunities. This paper proposes directional asynchronous full-duplex medium access control (DAFD-MAC) to avoid interference on primary and secondary nodes. DAFD-MAC suppresses the secondary transmission collision problem by sending a data frame with directional antennas and also a Network Allocation Vector (NAV) frame while receiving the data frame. The simulation results show that the proposed DAFD-MAC outperforms carrier sense multiple access/collision avoidance (CSMA/CA), full-duplex MAC (FD-MAC), and multi-hop full-duplex MAC (MFD-MAC).
