Cognitive Radio Networks (CRNs) are being studied intensively and gainingimportance as spectrum is the heavily underutilized. CRN has the capability toexploit smartly the unutilized frequency spectrum. Recently, the researchcommunity started to work in the area of cognitive radio routing. In a flattopology, all nodes are of the same level and functionality, thus making itsimple and efficient for smaller networks. However, when the network is largewith sparse nodes, the routing information becomes more complex makingcluster-based techniques really relevant to tackle such situations. In acluster-based routing, all nodes in the network are dynamically organized intopartitions called groups or clusters. In each cluster, a cluster head is chosento help in the data transmission management and to maintain cluster membershipinformation. This paper proposes a novel routing protocol for cognitive radioad hoc networks (CRAHNs) based on clustering model which amends swiftly to thetopological changes and establishes the routing efficiently. Our proposedapproach is thoroughly evaluated through simulation study. The results statethe suitability of the proposed protocol for cognitive radio ad hoc networksand demonstrate that it has better performance in terms of finding thesource-destination route, reducing the amount of messages that are transmittedall over the network and minimizing the routing delay.
