We study the physical-layer security of a cognitive radio system in the face of multiple
eavesdroppers (EDs), which is composed of a secondary base station (SBS), multiple …

In this paper, we consider an energy-harvesting underlay cognitive radio (CR) system, which
is comprised of multiple cognitive users (CUs), a common cognitive base station (CBS), and …

In this paper, we study energy harvesting cognitive radio networks (CRNs) in the presence
of multiple eavesdroppers (EAVs) and multiple primary users (PUs). In particular, the …

Herein, the authors consider harvested energy powered cognitive radio networks (CRNs) in
which harvested energy is stored in a rechargeable battery which has finite capacity. In …

This article investigates the physical layer security for a cooperative cognitive radio (CCR)
system with energy-harvesting (EH) technique, which consists of a cognitive source (CS) …

Physical-layer security (PLS) for an underlay cognitive radio network (CRN)-based
simultaneous wireless information and power transfer (SWIPT) over cascaded κ-µ fading …

In this paper, physical-layer security (PLS) of an underlay cognitive radio network (CRN)
operating over cascaded Rayleigh fading channels is examined. In this scenario, a …

Physical layer security is an important and timely topic in the research of future wireless
systems and it constitutes a part of the Internet of Things (IoT) notion. IoT oriented systems …

In this paper, we investigate the physical‐layer security in an energy‐harvesting (EH)
multiuser network with the help of a friendly jammer (J), where multiple eavesdroppers are …

This paper proposes a jamming technique which employs a self-powered secondary
jammer to interfere a wire-tapper, who eavesdrops communications between a self-powered …
