Preference-Based Spectrum Pricing in Dynamic Spectrum Access Networks [PDF]

open access: yesIEEE Transactions on Services Computing, 2018
With market-driven secondary spectrum trading, licensed users can receive benefits in terms of monetary rewards or various transmission services, thus setting a fair pricing structure by suitably defining spectrum quality characteristics and accurately addressing participant’s requirement is a key issue.

Admission Control and Interference Management in Dynamic Spectrum Access Networks

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
We study two important aspects to make dynamic spectrum access work in practice: the admission policy of secondary users (SUs) to achieve a certain degree of quality of service and the management of the interference caused by SUs to primary users (PUs ...

Dynamic Spectrum Access Techniques

open access: yes, 2013
It is now widely recognized that wireless communications systems don't exploit the whole available frequency band. The idea has naturally emerged to develop tools to better use the spectrum. Cognitive Radio (CR) is the concept that meets this challenge.
