Abstract : | This work investigates the effects of full duplexity on delay and throughput in interferencelimited multi-hop networks. It is assumed that transmission channel state information is not available and beamforming is employed as the transmission scheme. We derive a closed-form expression for hop success probability in networks of this type. We then compare the delay and throughput of multi-hop networks employing full duplex and half duplex beamforming. The delay and throughput are studied in two cases: when full duplexity is used for ”full duplex relay (FDR)” and ”bi-directional beamforming (BBF)”. For FDR, employing full duplex beamforming is more beneficial if a low rate constraint is required or if interferers are rare. However, this benefit diminishes as the required data rate or the interferer density increases. For BBF, the use of full duplex beamforming is always more beneficial because it leads to a reduction in the required rate constraint. Specifically, this benefit becomes more significant as the required rate rises and interferers become rarer. |
