We consider a cognitive radio network where multiple secondary users (SUs) coexist with a
primary user (PU). There exist multiple eavesdroppers (EAVs) who attempt to overhear the …

This paper investigates the impact of practical operation conditions such as channel
information imperfection (CII), independent nonidentical (ini) fading distributions, strict power …

This paper considers a cognitive radio network with a set of secondary users (SUs) who
share a spectrum band licensed to a primary user (PU). The PU is assumed to be …

This paper investigates the effect of imperfect channel information on the outage
performance of underlay cooperative cognitive networks with reactive relay selection under …

In this paper, we consider a spectrum sharing cognitive radio network where a secondary
user (SU) transmitter (SU-Tx) communicates with multiple SU receivers (SU-Rxs). There …

This paper analyzes outage performance of opportunistic relay selection in cognitive radio
networks with primary user's interference and direct channel over independent non …

This paper evaluates outage performance of reactive relay selection in cognitive radio
networks over Nakagami-m fading channels under consideration of imperfect channel …

This paper considers a cognitive radio (CR) network in the presence of a malicious
eavesdropper who attempts to receive confidential messages from a pair of primary users …

Cognitive radio network concept has been considered as a promising solution to improve
the spectrum utilization. However, it may be vulnerable to security problems as the primary …

The objective of this paper is to study the performance of a cognitive radio network (CRN)
under the influence of an eavesdropper (EAV) which can wiretap the primary user (PU) …
