Overlay networks allow the unlicensed transmitter (UT) to aid the licensed transmitter (LT) by
sending the superimposed signal including messages of both UT and LT with a higher …

This paper investigates the physical layer security (PLS) of non-orthogonal multiple access
(NOMA)-enabled overlay cognitive radio networks (NOMA-OCRNs), considering multiple …

We investigate the secrecy transmission of uplink non-orthogonal multiple access (NOMA)
with the aid of energy harvesting (EH) jammers. During each time frame, communication is …

In this paper, we evaluate the secrecy performance in terms of secrecy outage probability
(SOP) for Internet of things (IoT) enabled multi-relaying non-orthogonal multiple access …

In this paper, we present a physical-layer security scheme that exploits artificial noise (AN) to
secure the downlink legitimate communications and transfer energy to nodes operating …

In this paper, a down-link non-orthogonal multiple access (NOMA) system with imperfect
successive interference cancellation (SIC) using Energy-Harvesting untrusted relays is …

Main design objectives of future wireless networks are information security and efficient
spectrum-and-energy utilization to serve a tremendous number of users and applications …

In this paper, we investigate the physical-layer security for an Internet of Things (IoT)
relaying network employing non-orthogonal multiple access (NOMA) in the context of non …

This article focuses on covert communication in a distributed network with multiple
nonorthogonal multiple access (NOMA) systems, where each NOMA system is consisted of …

In this paper, we analyze the physical layer security (PLS) performance of nonorthogonal
multiple access (NOMA)‐enabled overlay cognitive radio networks (NOMA‐OCRNs) in the …
