In high-mobility Cognitive Radio Networks (CRNs), the fast topology changes increase the complexity of the routing scheme. In this paper, the authors propose a novel CRN routing scheme that considers the path stability and node capacity. First, a realistic mobility model is proposed to describe the movement of highly mobile airborne nodes and estimate the link stability performance based on node movement patterns. They also proposed a CRN topology management scheme based on a clustering model that considers radio link availability, and the Cluster Heads (CHs) are selected based on the node degree level, the average number of hops, and channel switching from member nodes to the CH.
