Abstract Device-to-Device (D2D) relayed communication helps in extending the coverage
range of cellular networks. Relay devices support multi-hop D2D communication where two …

We develop a comprehensive framework to characterize and optimize the performance of a
unmanned aerial vehicle (UAV)-assisted D2D network, where D2D transmissions underlay …

Unmanned aerial vehicle (UAV)-assisted base stations (BS) can keep the system
performance of the cellular networks with device-to-device (D2D) communications in the …

In this paper, we propose a novel optimization model for multiple Unmanned Aerial Vehicles
(UAVs) working simultaneously as relays to help two set of ground users; namely relay users …

In this letter, we aim to maximize the rate of a device-to-device (D2D) pair for a downlink
unmanned aerial vehicle (UAV)-aided wireless communication system, where D2D users …

The proliferation of mobile devices and data-hungry applications running on them leads to a
massive growth of wireless data traffic. Supporting this ever-increasing data demands and …

Device-to-Device (D2D) communication has been proven an efficient technique in the
present and upcoming cellular networks for improving network performance. Many a time, a …

The advanced Device-to-Device (D2D) system is recognized as one of the key emerging
technologies to support the increasing wireless data traffic of fifth generation (5G) systems …

Device-to-device (D2D) communication enables direct data transmissions between devices,
thereby filling in the blind zones of base stations (BSs) and alleviating their load pressures …

Device-to-device (D2D) communications allows user equipment (UE) that are in close
proximity to communicate with each other directly without using a base station. Relay …
