Cognitive radio (CR) technology offers a promising solutionto the spectrum scarcity problem via dynamic spectrum access(DSA). Due to the nature of cooperative cognitive radio networks(CRNs), where two distinct networks are active simultaneously, asignificant amount of control messaging is required in order to coordinatechannel access, schedule sensing, and establish and releaseconnections. Efficient control plane messaging can be achieved bythe selection of an appropriate control channel (CC). Major selectionstrategies of CCs are categorized as either dedicated or dynamicstrategies. This paper studies the major potential techniquesfor selecting reliable CCs for coordination and information distributionin license-exempt (LE) bands. This involves determining thepotential and limitations of each technique in terms of availability,complexity, and robustness. We consider real-life scenarios includingan outdoor stadium and an indoor environment. Recommendationsare given for different situations.
