With the advent of 5G and the need for energy-efficient massively connected wireless
networks, in this work, we consider an energy harvesting (EH) based multi-relay downlink …

Non-orthogonal multiple access (NOMA) is considered as one of the most promising
technologies to handle the issue of spectrum scarcity in beyond fifth-generation (5G) …

With the rapid growth of vehicles, the vehicular networks meet main challenges such as
dynamic, heterogeneous, and large scaled. In addition, the cellular-based vehicular …

Combining energy harvesting (EH) and device-to-device (D2D) communication underlaying
5G cellular networks is a very promising direction to improve both energy and spectral …

In this article, we introduce a small-cell network operating in the context of heterogeneous
cellular networks for both downlink (DL) and uplink (UL) by deploying three techniques of …

Blind-spots, where wireless signals do not reach within the coverage range, often emerge in
a dynamic environment due to obstacles, geographical location or mobility of cellular users …

In this study, a cooperative communication system that employs multiple decode-and-
forward relay nodes (RNs), in which the associated/active RNs perform phase rotation of the …

Abstract Device-to-device (D2D) communication is one of the key enabling technologies for
5G to support many connections efficiently. In a cooperative out-band D2D communication …

This article studies the wireless systems by implementing the full-duplex (FD) unmanned
aerial vehicle (UAV) relay to allow two nearby base stations joint communicate to distant …

Vehicle-to-everything (V2X) communications are regarded as the key technology in future
vehicular networks. V2X features promising benefits in providing efficient and reliable …
