Wideband sensing-based cognitive radio with simultaneous wireless information and power
transfer can be designed for efficient spectrum and energy usage. We first aim to maximize …

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 …

By harvesting energy from ambient radio frequency (RF) signals, significant progress has
been achieved in wireless networks self-maintaining their life cycles. Motivated by this and …

Cooperative cognitive radio (CCR) is a novel paradigm to improve both radio spectrum
efficiency and communication quality. In this paper, we consider a CCR network (CCRN) …

In this paper, we consider simultaneous wireless information-and-power transfer (SWIPT) for
a cooperative cognitive radio network (CRN). Herein, one secondary user (SU) among a …

In overlay hierarchical cognitive radio (HCR) networks, the primary system (PS) and the
secondary system (SS) can cooperate to exploit the spectrum resource more efficiently. In …

This paper considers cognitive radio networks (CRNs) utilizing multiple time-slotted primary
channels in which cognitive users (CUs) are powered by energy harvesters. The CUs are …

We study the performance optimization problem for a cognitive radio network with radio
frequency (RF) energy harvesting capability for secondary users. In such networks, the …

Motivated by the benefits of cognitive radio (CR), energy harvesting (EH), and backscatter
communication (BC) technologies to support Internet of Things (IoT) systems, we investigate …

We consider a spectrum sharing scenario where a secondary transmitter (ST) communicates
with its destination via a decode-and-forward secondary relay (SR) in the presence of …
