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 …

We consider a cognitive radio (CR) network with simultaneous wireless information and
power transfer (SWIPT) system having one base station (BS) with multiple antennas that acts …

We address the physical layer security (PHY-security) for an underlay single-input multiple-
output (SIMO) cognitive radio network using simultaneous wireless information and power …

In this paper, we investigate the physical-layer security of a secure communication in single-
input multiple-output (SIMO) cognitive radio networks (CRNs) in the presence of two …

This work explores the physical layer security of an underlay cognitive radio network (CRN)
in the presence of a powerful interferer called a primary transmitter (PT) under peak …

This paper investigates the secrecy outage performance of underlay cognitive radio
networks, in which a source in a secondary system transmits its confidential information to a …

The authors study the secure transmission design in random cognitive radio networks where
the primary users, the secondary users and the eavesdroppers are randomly distributed …

This paper investigates the secrecy performance of an underlay cognitive radio network
(CRN) with outdated channel state information (CSI) for two practical scenarios, ie, scenario …

In this paper, we evaluate the secrecy outage performance and throughput of a hybrid
cognitive radio network, where a secondary user (SU) accesses the primary spectrum either …

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