Nonterrestrial communications have emerged as a key enabler for seamless connectivity in
the upcoming generation networks. This kind of network can support high data rate …

The unmanned aerial vehicle (UAV) assisted transmission can significantly improve the
spectrum efficiency and coverage of the wireless communication network. The paper …

In this article, we investigate the performance of a piece-wise linear model of energy
harvesting-based multiuser overlay spectrum sharing system. Herein, an energy …

Grant-free (GF) transmission holds promise in terms of low latency communication by
directly transmitting messages without waiting for any permissions. However, collision …

This paper considers a cooperative cognitive radio network with two primary users (PUs),
and two secondary users (SUs) that enables two-way communications of primary, and …

In this work, performance of a simultaneous wireless information and power transfer (SWIPT)
enabled cooperative cognitive radio sensor network (CRSN) is explored over generalized …

Relay selection not only maintains but also improves the reliability of source-destination
communication when the direct communication link cannot be established because of deep …

This paper investigates the performance of overlay full-duplex cooperative cognitive radio
network in the presence of imperfect self interference cancellation over generalized fading …

In this paper, we investigate an overlay cognitive radio network (CRN) in which one user is
selected among multiple secondary users (SUs) to harvest energy from primary …

Wireless power transfer (WPT) is an effective way to prolong the lifetime of the energy-
constraint networks. In this paper, we investigate a wireless powered cooperative non …
