“…Considering the uniqueness of FD communication, various MAC protocols for wireless FD networks have been proposed. Such protocols are classified into two main types, i.e., header snooping-based FD MAC [4][5][6][7][8] and RTS/CTS-based FD MAC [9][10][11][12][13][14][15][16]. The difference between the two schemes is whether or not the network nodes exchange control frames for DATA-frame transmission with FD.…”

“…MAC protocols for distributed networks, e.g., multi-hop networks and wireless local area network (WLAN), have been designed based on carrier-sense multiple access with collision avoidance (CSMA/CA). Two main types of CSMA-based FD MAC have been proposed; header snooping-based FD MAC [4][5][6][7][8] and request to send/clear to send (RTS/CTS)-based FD MAC [9][10][11][12][13][14][15][16]. The difference between the two schemes is whether or not network nodes exchange control frames prior to a DATA-frame transmission with FD communication.…”

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.

“…Obviously, this will increase the system hardware component, system complexity, deployment cost, power consumption and introduce synchronization challenges. In recent times, due to advancement in digital electronics technology, the use of a single antenna in a full-duplexing (FD) mode is possible where a single antenna can transmit and receive data simultaneously using the same time and frequency [8]. Use of a single antenna at the LR in FD mode will reduce the number of nodes and eventually lower the cost and power consumption.…”

Information secrecy is achievable in a broadcast wireless communication system when the adversary channel witness a greater disruption as against the main channel. The secrecy level need to be enhanced as the adversary terminal can use advance method to eaves drop the hidden message being exchanged between the two legitimate communicating partners. The use of relay-assisted node in information-theoretic approach at the physical layer security has been widely researched into but they are mostly operate in a half-duplex mode (HD). With the advancement in electronic technology, the use of a single antenna in full duplex mode (FD) is possible. We explore this property in enhancing the security of a broadcast wireless system at the physical layer. In this work, the transmitter generates artificial noise (AN) while the legitimate receiver(LR) also transmits another jamming noise (JN) from its antenna to unintended receiver (UR) node. The effect of these multiple noises are examined on the secrecy capacity and probability outage capacity on the UR channel. Mathematical analysis and the numerical simulation results show improvement in channel secrecy capacity over the conventional approaches.Index Terms-Artificial noise, full-duplex, physical layer security secrecy, outage probability

“…One of the main problems in full-duplex communications like the secondary collision problem, that occurs while combining wireless full-duplex with multi-hop communication, is avoided by using directional asynchronous full-duplex medium access control (DAFD-MAC) protocol and directional antennas [62]. Authors in [62] also focused on asynchronous timing adjustment because clock synchronization for all nodes in a multi-hop network is an unsettling task.…”

Full-duplex communication has attracted significant attention as it promises to increase the spectral efficiency compared to half-duplex. Multi-hop full-duplex networks add new dimensions and capabilities to cooperative networks by facilitating simultaneous transmission and reception and improving data rates.When a relay in a multi-hop full-duplex system amplifies and forwards its received signals, due to the presence of self-interference, the input-output relationship is determined by recursive equations. This thesis introduces a signal flow graph approach to solve the problem of finding the input-output relationship of a multi-hop amplify-and-forward full-duplex relaying system using Mason's gain formula. Even when all links have flat fading channels, the residual self-interference component due to imperfect self-interference cancellation at the relays results in an end-to-end effective channel that is an all-pole frequency-selective channel. Also, by assuming the relay channels undergo frequency-selective fading, the outage probability analysis is performed and the performance is compared with the case when the relay channels undergo frequency-flat fading. The outage performance of this system is performed assuming that the destination employs an equalizer or a matched filter.For the case of a two-hop (single relay) full-duplex amplify-and-forward relaying system, the bounds on the outage probability are derived by assuming that the destination employs a matched filter or a minimum mean squared error decision feedback equalizer. For the case of a three-hop (two-relay) system with frequency-flat relay channels, the outage probability analysis is performed by considering the output SNR of different types of equalizers and matched filter at the destination. Also, the closed-form upper bounds on the output SNR are derived when the destination employs a minimum mean squared error decision feedback equalizer which is used in outage probability analysis. It is seen that for sufficiently high target rates, fulli duplex relaying with equalizers is always better than half-duplex relaying in terms of achieving lower outage probability, despite the higher RSI. In contrast, since fullduplex relaying with MF is sensitive to RSI, it is outperformed by half-duplex relaying under strong RSI.ii ACKNOWLEDGMENTS I would like to express my gratitude to my supervisor, Dr. Cihan Tepedelenlioglu, for his support and supervision. His guidance and encouragement have been key in making this work a success.
