The integration of simultaneous wireless information and power transfer (SWIPT) and
cooperative relay (CoR) techniques has evolved as a new phenomenon for the next …

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 …

Relay selection is proposed in this paper as an efficient solution to secure information
transmission of secondary users against eavesdroppers in energy harvesting cognitive …

In this paper, we focus on the issue of energy efficiency (EE) optimization of amplify-and-
forward-based energy harvesting two-way relaying systems. Utilizing the statistical channel …

In this paper, we investigate secure communications in energy harvesting enabled
cooperative cognitive radio networks (CCRNs). In such CCRNs, a pair of primary users …

This study suggests an energy‐scavenging capable unlicensed relay not only to retain
communications between an unlicensed sender‐recipient pair in underlay cognitive …

In this paper, we propose an exact closed-form expression of secrecy outage probability
(SOP) for underlay cognitive network with energy scavenging capable relay over Nakagami …

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 …

An unlicensed relay is located between an unlicensed sender and an unlicensed recipient
for securing the sender's message against a wire-tapper in underlay cognitive networks …

Physical layer security in relay based cooperative networks is a promising approach to
maintain confidentiality of information. In this paper, secrecy performance of a dual hop …
