Joint Channel

In Cognitive Radio Networks (CRNs) there is much dynamicity due to the activities of primary users which results in instability of routes. Therefore, an efficient routing protocol based on good channel assignment strategy is required in CRNs. A good channel selection strategy makes route stable by selecting channels having larger capacity and greater availability time. Therefore, the focus of this chapter is joint channel assignment and routing in CRNs, which provides a comprehensive survey on routing and channel assignment in CRNs. First, the importance of joint channel assignment and routing for successful communication in cognitive radio networks is discussed. Then classification and challenges related to channel assignment and routing are discussed in detail. In order to establish reliable routes in CRNs, some factors are discussed that further enhance the communication in CRNs. Finally, guidelines for the development of efficient routing protocols are discussed.
