With the rapid development of the Internet of Things (IoT), non-Orthogonal Multiple Access
(NOMA) technology and cognitive wireless network are two promising technologies to …

In cognitive radio networks, signal transmission is easily attacked by eavesdroppers due to
the broadcast characteristics of wireless media. The security of the network requires great …

In this article, we investigate physical layer security (PLS) in non-orthogonal multiple access-
enabled (NOMA-enabled) underlay cognitive radio networks (CRNs) with outdated channel …

In this paper, we investigate the physical-layer security of a secure communication in single-
input multiple-output (SIMO) cognitive radio networks (CRNs) in the presence of two …

The combination of Cognitive Radio with Nonorthogonal Multiple Access (CR-NOMA) has
enormous potential interest to improve spectral efficiency and increase system capacity in …

This paper investigates physical layer security (PLS) in nonorthogonal multiple access-
enabled (NOMA-enabled) cognitive radio networks (CRNs). Considering an existing …

This paper investigates physical layer security (PLS) in cognitive radio inspired non-
orthogonal multiple access (CR-NOMA) networks with multiple primary and secondary …

In this study, the physical layer security for cognitive radio network (CRN) will be
investigated in which a secondary user transmitter (SU-Tx) sends confidential information to …

In this paper, we consider a secrecy transmission scheme based on physical layer,
employing multi-band transmitters with dynamic power allocations and channel selections …

In this paper, we consider a cognitive radio network that consists of one cognitive base
station (CBS) and multiple cognitive users (CUs) in the presence of multiple eavesdroppers …
