The stringent requirements of wireless multimedia transmission lead to very high radio
spectrum solicitation. Although the radio spectrum is considered as a scarce resource, the …

Ambient backscatter (AB) communications and radio frequency (RF)-powered cognitive
radio networks (CRNs) address the concerns of energy and spectrum scarcities from …

This article focuses on the issue of cooperative spectrum sensing (CSS) in a mobile energy-
harvesting cognitive radio network (EH-CRN), where secondary transmitters (STs) are …

With the evolution of Internet of Things (IoT), some IoT nodes possess a certain degree of
mobility, and the gains of the corresponding channels vary dramatically, incurring the energy …

This paper aims to investigate the impacts of sensing energy and data availability on the
secondary throughput of energy harvesting cognitive radio networks (EH-CRNs), where …

The UAV-assisted energy harvesting cognitive wireless network has the feature of fast
layout, remarkable spectrum efficiency (SE) and energy efficiency (EE), thereby being …

Motivated by the benefits of cognitive radio (CR), energy harvesting (EH), and backscatter
