This paper studies the secondary network relying relay selection to transmit signal from the
secondary source (base station) to two destinations. Especially, two destinations are …

This paper studies a downlink security-aware secure outage performance in the secondary
network of cognitive radio-assisted non-orthogonal multiple access network (CR-NOMA) …

Cognitive radio (CR) technology can be used as a key technology for wireless
communication to integrate heterogeneous networks, increasing channel capacity and …

This paper presents a controllable analysis framework for evaluating the reliability and
security of underlay cognitive radio networks (CRs) relying on non-orthogonal multiple …

This article studies the interweave cognitive network with non-orthogonal multiple access
(NOMA) principle under the appearance of one eavesdropper. The best relay selection …

Recently, physical-layer security (PLS) has been reported in many literature (ie,[1]-[4]) as an
efficient approach to obtain security for wireless communication systems. For the secure …

In this paper, we investigate the secrecy performance of the cooperative non-orthogonal
multiple access (NOMA) network with radio frequency (RF) power transfer. Specifically, this …
