Vehicular communication has been envisioned to support a myriad of essential fifth-
generation and beyond use-cases. However, the increasing proliferation of smart and …

This paper investigates the joint impact of nodes' mobility and imperfect channel estimates
on the secrecy performance of an underlay cognitive radio vehicular network over Nakagami …

Herein, we consider an underlay cognitive radio network (CRN) where mobile secondary
user wishes to transmit a confidential information to the secondary destination in the …

In this paper, we address the physical-layer security issue of a secondary user (SU) in a
spectrum-sharing cognitive radio network (CRN) from an information-theoretic perspective …

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(CRN) with outdated channel state information (CSI) for two practical scenarios, ie, scenario …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 contrast with the traditional cryptography, physical layer security has attracted the
attention of many researchers having aim at reinforcing the security of communication …

In this paper, we present a method of utilizing channel diversity to improve the secrecy
outage probability and the intercept probability in a cognitive radio (CR) network. With the …

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 …

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 intervehicular cognitive relaying
network. We assume that the primary receiver (PU) in the primary network is fixed, whereas …
