This letter investigates secrecy performance for cognitive transmissions, where a secondary
user (SU) shares same spectrum with a primary user (PU) simultaneously ensuring the …

This paper studies the physical layer security issue for cognitive radio sensor networks
(CRSNs) with primary outage constraint, for which a tractable framework is developed to …

This study investigates the physical‐layer security in random cognitive radio network (CRN)
consisting of randomly distributed primary nodes, secondary nodes, relay nodes and …

Abstract Cognitive Radio Networks (CRNs) have been obtained a significant focusing due to
the ability of this technology to dissolve the issues of spectrum overcrowding and …

In this paper, we investigate the secrecy performance of a Cooperative Cognitive Radio
Network (CCRN) in the presence of an eavesdropper (EAV). The secondary users (SUs) are …

In Rician-fading scenario, cognitive radio networks (CRNs) with a source (S) in a secondary
system transmitting its confidential information to a legitimate destination (D) in the presence …

Cognitive radio technology is the vision of pervasive wireless communications that improves
the spectrum utilization and offers many social and individual benefits. The objective of the …

This paper studies the physical layer security (PLS) in an underlay cognitive radio (CR)
network. Under an interference constraint set by the primary user, we propose a secure …

The concept of secrecy outage probability is a fundamental aspect used to study the
performance of secrecy in wireless communication networks. While this metric constitutes …

Recent development in wireless communications has lead to the problem of growing
spectrum shortage. Cognitive radio, as a novel technology, has been proposed in recent …
