How to achieve energy-efficient transmission in energy harvesting cognitive radio network
(EH-CRN) is of great importance when nodes in EH-CRN are self-maintained. This paper …

Recent advancement in wireless communications demands high data rate transmission at
low power consumption. To this aim, the present work proposes an energy harvesting based …

Motivated by the dilemma in the multi-channel spectrum sensing by the multi-antenna user,
this paper focuses on the scheme of spectrum sensing and energy harvesting to coordinate …

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 …

In this letter, we analyze an energy-harvesting-based cognitive radio (CR) system. The CR
system harvests energy from the radio frequency (RF) signal of primary user (PU) during …

Wireless devices' energy efficiency and spectrum shortage problem has become a key
concern worldwide as the number of wireless devices increases at an unparalleled speed …

Due to the scarcity of the allocated spectrum and power supply of wireless sensor networks,
Cognitive Radio Networks (CRN) and Energy Harvesting (EH) techniques have extensively …

In this paper, we consider an energy harvesting cognitive radio network (EH-CRN), where a
primary and a secondary user coexist in underlay mode. Both the transmitters have energy …

In this paper, we study energy harvesting cognitive radio networks (CRNs) in the presence
of multiple eavesdroppers (EAVs) and multiple primary users (PUs). In particular, the …
