In the present contribution, we propose a novel opportunistic ambient backscatter
communication (ABC) framework for radio frequency (RF)-powered cognitive radio (CR) …

This paper introduces a new solution to improve the performance for secondary systems in
radio frequency (RF) powered cognitive radio networks (CRNs). In a conventional RF …

In this paper, we propose a novel network model for RF-powered cognitive radio networks
and ambient backscatter communications. In the network under consideration, each …

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 …

In this paper, we study radio frequency (RF)-powered underlay cognitive radio networks
(CRNs) with power-domain non-orthogonal multiple access (NOMA). In these networks, by …

In this paper, we investigate the dynamic access point and service selection in a backscatter-
assisted radio-frequency-powered cognitive network, where many secondary transmitters …

Cognitive radio has attracted an increasing amount of interest over the past few years as an
effective method of alleviating the spectrum scarcity problem in wireless communications …

For an RF-powered cognitive radio network with ambient backscattering capability, while the
primary channel is busy, the RF-powered secondary user (RSU) can either backscatter the …

In this paper, we introduce a new model for RF-powered cognitive radio networks with the
aim to improve the performance for secondary systems. In our proposed model, when the …

In this paper, we study the transmission strategy adaptation problem in an RF-powered
cognitive radio network, in which hybrid secondary users are able to switch between the …
