In this paper, the authors present a solution for the realization of large cognitive radio networks. The solution features a spectrum-aware neighbor discovery and clustering scheme that works in conjunction with a network coded cognitive control channel in order to allow cognitive radio devices to opportunistically access the unused spectrum. They evaluate the performance of the proposed solution with respect to the characteristics of the formed clusters as well as the reliability of the dissemination of the control information within the cluster.
