At present, the fifth generation (5G) communication networks are in the time of large‐scale
deployment principally because its characteristics consists of large bandwidth, fast …

In recent years, the access of massive communication devices leads to the insufficient
spectrum resources of wireless networks. One of the practical means to resolve the problem …

In this paper, the secure communication of a cognitive radio network (CRN) over Nakagami-
m fading channel is investigated. An underlay protocol is used in the considered network …

With the development of Internet of Things (IoTs), devices are now connecting and
communicating together on a heretofore unheard‐of scale, forming huge heterogeneous …

This paper investigates the secrecy performance of a single-input multiple-output (SIMO)
based underlay cognitive radio networks. In particular, a single-antenna secondary …

In this letter, we consider a single-input multiple-output cognitive wiretap system over
generalized-K channels, where the eavesdropper overhears the transmission from the …

This paper investigates the intercept probability (IP) performance for a dual-hop multi-
secondary user (SU) underlay cognitive-radio networks. Whereby, the relay R is self …

The presence of correlated and imperfect channel state information (CSI) affects the secrecy
performance of cognitive radio networks (CRN). In this paper, we propose a physical layer …

In this paper, we compute the primary exclusive region (PER) and the secrecy capacity at a
primary receiver in a fading cognitive radio network. We consider Rayleigh fading and log …

In this paper, we investigate the secondary network physical layer security under the outage
constraint of the primary user (PU) receiver and interference from the PU transmitter to the …
