“…This simulation deploys the Relay Full-Duplex MAC protocol [23] by extending the Wi-Fi module [2] of NS-3.20. Relay Full-Duplex MAC (RFD-MAC) [23] is a media access control protocol which is designed for relay full-duplexing. Multi-hop networks can handle bidirectional full-duplexing as well as relay full-duplexing.…”

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.

“…Some proposals aim at exploiting FD operation to allow nodes to transmit concurrently as primary or secondary transmitters and receivers and allow relaying nodes to receive transmissions while forwarding their own [11], [18], [19]. Other proposals [2], [24] focus on the interplay between the up-link and down-link with an access point of a wireless LAN or base stations in 5G wireless networks.…”

Abstract-Carrier-Sense Multiple Access with Collision Avoidance and Detection (CSMA/CAD) is introduced and analyzed. The new protocol operates in a single channel and consists of taking advantage of self-interference cancellation to enable collision detection (CD) in the context of collision-avoidance (CA) handshakes in multi-hop wireless networks. It is shown that CSMA/CAD eliminates the collisions of data packets in the presence of hidden terminals. The throughput of CSMA/CAD is analyzed and compared with the throughput of CSMA, CSMA/CA, and dual busy-tone multiple access (DBTMA). The analysis results show that CSMA/CAD provides better performance than the other channel-access schemes aimed at combating hidden terminals, and that the throughput degradation due to hidden terminals in CSMA/CAD is limited compared to CSMA.
