The cognitive radio paradigm will allow the formation of spontaneous wireless networks able to communicate in spectrum bands temporarily left free by licensed primary users. The behavior of the primary users has a high influence on the network connectivity and impacts the performance of the Cognitive Radio Network (CRN). When an ad-hoc network is established among cognitive radio nodes, not only the position of nodes but also the activity of the primary users impacts the network connectivity. The aim of this paper is twofold: on one side it provides a methodology to evaluate the k-connectivity of a cognitive radio ad-hoc network.
