This paper presents the joint design of network coding and backpressure algorithm for cognitive radio networks and its implementation with software-defined radios (SDRs) in a high fidelity network emulation testbed. The backpressure algorithm is known to provide throughput optimal solutions to joint routing and scheduling for dynamic packet traffic. This solution applies to cognitive radio networks...
This paper presents a distributed cognitive radio network architecture for joint routing and spectrum access, its implementation with software-defined radios (SDRs), and its evaluation in a high-fidelity emulation testbed. CREATE-NEST, a comprehensive cognitive radio system, is built as an experimental prototype that provides a Cognitive Radio nEtworking ArchiTecturE (CREATE) for distributed support...
