Routing protocol for directional full-duplex wireless

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 end-to-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.
