The Cognitive Radio and the Cognitive Radio Networks have recently become one of the
most intensively studied paradigms in wireless communications. The main distinctive …

This paper provides an overview of cognitive radio technology and its applications in the
field of civil aviation. Cognitive radio technology is a relatively new and emerging field that …

The concept of Cognitive Radio (CR) has emerged as a practical solution to solve the issue
of the fixed spectrum and bandwidth scarcity in wireless communication. However, the …

We consider a cognitive wireless network in which users adopt a spectrum sharing strategy
based on cooperation constraints. The majority of cognitive radio schemes bifurcate the role …

The Coase theorem suggests that a regulatory scheme, which clearly defines spectrum
property rights and allows transactions between participants, induces an optimal spectrum …

Cognitive radio networking has recently presented itself as a key technology to alleviate the
severe spectrum underutilization and provide a solution for spectrum scarcity. Cognitive …

A cognitive radio network has a high promise to improve spectrum utilization, through
exploitation of spectrum holes from the primary network. However, in a distributed …

In multichannel, cognitive radio (CR), the secondary user (SU) is allowed to utilize multiple
subaltern frequency bands of the primary user (PU), when these bands, namely …

This chapter sets the stage for the rest of book by presenting the current state of affairs in the
management of radio spectrum and related standardisation and regulatory initiatives …
