In this paper, we consider a cooperative cognitive radio non-orthogonal multiple access
network, where a secondary transmitter (ST) assists transmission of a primary source …

In this paper, we consider a cooperative multi-hop secured transmission protocol to underlay
cognitive radio networks. In the proposed protocol, a secondary source attempts to transmit …

In this paper, the secrecy outage performance of an underlay cognitive decode-and-forward
relay network over independent but not necessarily identical distributed Nakagami-m fading …

In this letter, we consider an underlay cognitive radio network in which a secondary
transmitter (ST) communicates with a secondary destination (SD) with the aid of multiple …

This paper investigates the secrecy performance of amplify-and-forward (AF)-relaying
cooperative cognitive radio networks (CCRNs) over Rayleigh-fading channels. Specifically …

In this paper, we propose a security-oriented transmission scheme with the help of multiple
relays in Cognitive Radio (CR). To maximise the Secrecy Capacity (SC) of the source …

In this paper, we investigate cooperative secure communications in a four-node cognitive
radio network where the secondary receiver is treated as a potential eavesdropper with …

In this paper, we investigate the secrecy outage performance of the decode-and-forward
cognitive relay network with the existence of the co-channel interference, where all nodes …

This paper investigates the physical layer security problem of cognitive decode-and-forward
relay networks over Nakagami-m fading channels. We consider the relaying communication …

In this paper, the security performance of a dual-hop underlay cognitive radio (CR) system is
investigated. In this system, we consider that the transmitted information by a source node S …
