Ergodic Secrecy Rate of Optimal Source-Destination Pair Selection in Frequency-Selective Fading
IEEE Transactions on Vehicular Technology, 2023 Node selection is a simple technique to achieve diversity and thereby enhance the physical layer security in future wireless communication systems which require low complexity. High-speed data transmission often encounters frequency selective fading. In this context, we evaluate the exact closed-form expression for the ergodic secrecy rate (ESR) of the

Secrecy Rate Region Enhancement in Multiple Access Wiretap Channel
Journal of Telecommunications and Information Technology, 2022 It is commonly known that physical layer security is achieved with a trade-off in terms of the achievable rate. Hence, security constraints generate rate losses in wiretap channels.

Transmitter selection for secrecy against colluding eavesdroppers with backhaul uncertainty
IET Communications, 2023 Due to the exponential growth of interconnected devices and reduced cell coverage, beyond fifth‐generation networks will be dense. Thus, instead of wired backhaul, wireless backhaul will be cost‐effective and flexible.

Secure Energy Harvesting Relay Networks With Unreliable Backhaul Connections
IEEE Access, 2018 Wireless backhaul is a cost-effective and flexible alternative to wired backhaul, yet it suffers from unreliability. This paper studies the secrecy performance of a relay network with such unreliable wireless backhaul.
