Non-orthogonal multiple access (NOMA) is considered to be one of the best candidates for
future networks due to its ability to serve multiple users using the same resource block …

In this letter, we investigate the secrecy outage performance of a cooperative non-
orthogonal multiple access (NOMA) network, where a base station (BS) communicates with …

Three relay selection techniques, aiming at achieving secure non-orthogonal multiple
access in cooperative energy-harvesting (EH) communications, are proposed and …

In this paper, we analyze the secrecy and throughput of multiple-input single-output (MISO)
energy harvesting (EH) Internet of Things (IoT) systems, in which a multi-antenna base …

This letter considers a trusted decode-and-forward relay-assisted two-user non-orthogonal
multiple access (NOMA) communication system, and tackles the secure rate maximization …

Aiming at high energy consumption and information security problem in the simultaneous
wireless information and power transfer (SWIPT) multi-user wiretap network, we propose a …

In this paper, we study the physical layer security in the downlink Non-Orthogonal Multiple
Access (NOMA) systems with the capability of simultaneous wireless information and power …

In this paper, we propose a novel opportunistic scheduling-based antenna-user selection
(OBAUS) scheme to improve the secrecy performance of cooperative non-orthogonal …

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 …

This paper studies the physical layer security for a cooperative non-orthogonal multiple
access system with energy harvesting (EH) and full-duplex (FD) relaying. In particular, the …
