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 …

Cognitive radio has emerged as an essential recipe for future high-capacity, high-coverage
multitier hierarchical networks. Securing data transmission in these networks is of the utmost …

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 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 joint impact of nodes mobility and imperfect channel
estimates on the secrecy performance of a cognitive vehicular radio network under time …

The secure transmission of confidential information in cellular vehicle-to-everything (C-V2X)
communication networks is vitally important for user's personal safety. However, for C-V2X …

This paper considers a relay-based underlay cognitive radio vehicular network, where a
secondary source vehicle transmits information to a secondary destination vehicle with a …

This paper studies the physical layer security of a vehicular communication network in the
presence of interference constraints by analysing its secrecy capacity. The system considers …

This paper investigates the secrecy performance of an underlay cooperative cognitive
relaying network, wherein a secondary source vehicle communicates with a fixed secondary …
