A Centralized Model Enabling Channel Reuse for Spectrum Allocation in Cognitive Radio Networks
Cybernetics and Information Technologies, 2021 Cognitive Radio (CR) is an advanced technology, which intends to boost the radio spectrum utilization. On perceiving the spectrum holes, next there is a need to provide a fair distribution of the vacant licensed channels amongst Secondary Users (SUs ...

Managing Policies for Dynamic Spectrum Access [PDF]
, 2006 The advent of software radio technology and the resulting potential for dynamic access to the radio spectrum presents major new challenges in managing that access. These challenges arise from the likely spread of spectrum access decision-making authority well beyond existing regulatory authorities to a wide variety of co-existing market-based or open ...

Over-Booking Approach for Dynamic Spectrum Management [PDF]
, 2011 An over-booking based dynamic spectrum management (DSM) scheme is conceived for improving the attainable spectral efficiency. All secondary users (SU) will be categorized into different classes and they borrow spectral resources from the primary users ...

Coordinating standardization in Dynamic Spectrum Access
2014 IEEE Globecom Workshops (GC Wkshps), 2014 This paper investigates the gap between research into Dynamic Spectrum Access (DSA), and the standardization of these technologies, as well as ways in which coordination of standardization activities between EU funded research projects might help bridge this gap. Concretely, it first discusses the current state of standardization in CR and DSA, as well

Coopetition spectrum trading in cognitive radio networks [PDF]
, 2013 Spectrum trading is a promising method to improve spectrum usage efficiency. Several issues must be addressed, however, to enable spectrum trading that goes beyond conservative trading idle bands and achieve cooperation between primary and secondary ...
