Abstract
Medium access control (MAC) protocol operations for in-band full duplex multi-hop networks play an important role in efficient data relaying and throughput enhancement. Knowledge of the relationship between essential operations in MAC protocol for full duplex MAC (FD MAC) networks and network performance is important and useful in terms of the protocol and network design. FD MAC protocols often require exchanging control frames, e.g., request to send/clear to send (RTS/CTS). However, the conventional model cannot analyze the performance of wireless multi-hop networks with RTS/CTS-based FD MAC. Thus, this paper proposes a throughput analysis model for wireless multi-hop networks with RTS/CTS-based FD MAC. The proposed model includes novel “airtime expressions”, which allows us to handle RTS/CTS operations under FD MAC. The proposed model provides the end-to-end throughput of multi-hop networks with RTS/CTS-based FD MAC for any number of hops and any payload size. The validity of the analytical expressions is confirmed through comparisons with simulation results.

Because the model is specified for the evaluations of the performance proposed in [14], extending the model to a general analytical model, which takes into account the essential behaviors in multi-hop networks, such as collisions induced by hidden nodes and Network Allocation Vector (NAV) operation, under the use of RTS/CTS-based full duplex MAC (FD MAC)
Summary
The wireless full-duplex (FD) communication technique has attracted research attention. Throughput analysis for CSMA/CA-based FD multi-hop networks has been proposed previously [17]; the model [17] cannot analyze the performance of wireless FD multi-hop networks with RTS/CTS-based FD MAC. Clarifying the relationship between the network performance and essential behavior of multi-hop networks under the use of RTS/CTS-based FD MAC theoretically is useful for the protocol design and the optimization. The performance analysis and future protocol design for FD multi-hop networks require the establishment of an analytical model for multi-hop networks with RTS/CTS-based FD MAC. This paper proposes a throughput analysis model for wireless multi-hop networks with RTS/CTS-based FD MAC.
