Survey on Spectrum Allocation Algorithms for Cognitive Radio Networks
the increasing growth of spectrum requirement has outpaced available spectrum resources.Cognitive Radio Network (CRN) has emerged as a promising solution to address the above dilemma by dynamically sharing spectrum among users.Recently
CRN technology has attracted great research interests as well as efforts.In this paper
we review the state-of-the-art of spectrum allocation techniques in CRNs.We first illustrate the technical background of CRNs
and then analyze the key issues in spectrum allocation algorithms design.Following that we review the design rationale and technical feature of typical allocation models
and further investigate the implementation mechanism of classical algorithms for each model.Finally
we envision the possible issues for future work on spectrum allocation.
