In cognitive radio networks, the media access control (MAC) protocols need to determine the
availability of spectrum resource through spectrum sensing and coordinate with the other …

Blockchain-based dynamic spectrum sharing (DSS) is viewed as a robust measure to
address the management and allocation of spectrum resources for Internet of Things (IoT) …

Over the past few years, dynamic spectrum access has been gaining an increasing attention
as a solution to the spectrum scarcity problem. In this paper, a primary user detection …

In this paper, a novel GPS-assisted grouping scheme is proposed to reduce the operational
cost of cognitive radio networks with femtocells. This scheme allows the cognitive base …

Dynamic spectrum access is an important step in the spectrum resource sharing process.
However, in the case of unknown spectrum access environment and dynamic model, it is …

A new era of communication is about to begin with the arrival of 6 G technology, which
promises previously unheardof speeds and bandwidth capacities. To fully realize the …

Spectrum trading is one of the most promising approaches to enabling dynamic spectrum
access (DSA) in cognitive radio networks (CRNs). With this approach, unlicensed users (aka …

This Chapter introduces the cognitive radio network as one of the most promising
technologies for the immediate and very near future. It explores its rich history and …

Spectrum trading is one of the most promising approaches to enabling dynamic spectrum
