Device-to-Device (D2D) communication has emerged as a promising technology for
optimizing spectral efficiency in future cellular networks. D2D takes advantage of the …

The integration of cognitive radio and device-to-device (D2D) communication gives rise to
Cognitive D2D (cD2D) communication, which offers numerous advantages, such as …

In this paper, we investigate the secrecy performance of dual-hop randomize-and-forward
(RaF) cognitive wiretap networks over Rayleigh fading channels, in which the RaF relay is …

In 5G networks, most D2D work focuses on optimizing system throughput without addressing
economic constraints. This article encourages users to exchange resources and apply …

This paper studies the secure transmission in the dual-hop cognitive wiretap networks,
where the secondary transmitter (Alice) aims to transmit confidential information to the …

Device-to-device communication allows a cellular user (relay node) to relay data between
the base station (BS) and another cellular user (destination node). We address the problem …

Device-to-device (D2D) communications are valuable in several domains, such as data
offloading and diffusion, as their cost is only a fraction of what regular cellular …

Device-to-Device communication allows a cellular user (relay node) to relay data between
the base station (BS) and another cellular user (destination node). We address the problem …

Cyber-physical systems (CPS) are complex networked systems that consist of cyber
components for computation and communication, closely interacting with physical …
