    Performance analysis of an in-band full-duplex MAC protocol for future wireless networks
    (IEEE, 2024-03) Sarmad, Wardah; Shahid, Syed Maaz; Karasan, Ezhan; Kwon, Sungoh
    In this article, we extend IEEE 802.11 from carrier-sense multiple access with collision avoidance to carrier-sense multiple access with collision detection (CSMA/CD) for in-band full-duplex (IBFD) wireless systems by utilizing the capabilities of full-duplex. In IBFD communications, nodes can effectively apply CSMA/CD but this may result in false alarms and missed collision detection due to residual self-interference. To analyze the performance of medium access control (MAC) protocol for an IBFD communications system, first, a Markov chain-based analytical model is designed for a CSMA/CD-based IEEE 802.11 distributed coordination function with IBFD capabilities. Then, the analytical expressions for goodput and packet loss probability are driven to investigate the impact of various parameters, including contention window size, packet length, and the number of nodes, on the performance of the designed model in the presence of sensing errors. The accuracy of the analytical model is validated by comparing the numerical and simulation results for saturated traffic conditions.
