Cognitive Radio Networks are expected to resolve important technological and operational challenges of future networks, such as Dynamic Spectrum Access, routing in heterogeneous networks and provisioning of Quality of Experience for different applications. Accordingly, a number of new terminal and network functionalities are required to solve the technical problems and to provide efficient management. The paper advances a new solution for routing in Cognitive Radio Networks, providing communication between Secondary Users occupying different socalled Spectrum Opportunities, i.e., portions of spectrum not occupied by Primary Users. This entails solving a complex process composed by two fundamental elements. These are the multi-constraint routing and the multi-dimensional adaptation for multiple cognitive radio dimensions like space, frequency, power and time. The goal of the paper is to develop optimization algorithms necessary to provide end-to-end routing paths for communication between Secondary Users with associated Quality of Experience demands.
