This paper provides an overview of the use of small cells (eg, femtocells) in the Internet of
Things (IoT) environments. As a result of rapid increase in the number of mobile connected …

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 …

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 …

The Internet of Bodies (IoBs) is an imminent extension to the vast Internet of Things domain,
where interconnected devices (eg, worn, implanted, embedded, swallowed, etc.) are located …

Cyber-security threats and issues have been exponentially increasing over the last two
decades, including in cognitive radio networks. These attacks and vulnerabilities negatively …

Cooperative and cognitive non-orthogonal multiple access (CCR-NOMA) has been
recognized as a promising technique to overcome spectrum scarcity and massive …

On the contrary of low speed and high delay acoustic systems, underwater optical wireless
communication (UOWC) can deliver a high speed and low latency service at the expense of …

In order to design energy efficient and energy harvesting (EEH) cooperative spectrum
sensing (EEH-CSS), four fundamental constraints must be considered: 1) collision constraint …

The conflation of cognitive radio (CR) and non-orthogonal multiple access (NOMA) concepts
is a promising approach to fulfill the massive connectivity goals of future networks given the …

Energy harvesting (EH) and spectrum harvesting (SH) are two promising and useful green
communication and networking mechanisms for the next-generation wireless networks …
