In this study, the secrecy performance of cooperative half‐duplex cognitive relay networks
(CRNs) comprised of multiple primary users (PUs) and multiple eavesdroppers under the …

In this, we propose a generalized partial relay selection (PRS) protocol to enhance the
secrecy performance for cooperative cognitive radio networks (CRNs) in terms of the …

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

We study the physical-layer security of multi-hop secondary network under spectrum sharing
constraint caused by the primary, which consists of many simultaneously independent direct …

In this paper, we investigate the secrecy performance of dual-hop decode-and-forward
cognitive relay networks taking into account the channel correlation between the main and …

In this paper, we consider cognitive relay networks with N th best relay and beamforming
schemes under the joint impact of imperfect spectrum sensing and outdated channel …

In this paper, we investigate the secrecy outage performance of decode-and-forward (DF)
buffer-aided multi-antenna underlay cognitive relay networks (CRNs) in the presence of an …

In this paper, we study the secrecy performance of a half-duplex cognitive relay network in
the presence of multiple eavesdroppers and multiple primary users. In particular, generic K …

In this paper, we investigate the secrecy performance of cognitive radio networks (CRNs)
with full-duplex (FD) relaying over Rayleigh channels, where the secondary transmitter …

In this paper, we investigate the secrecy outage probability in a dual-hop decode-and-
forward (DF) secondary cognitive radio network, which is equipped with one source, one …
