Jabbari, BijanBaharlouei, Akram2013-08-092013-08-092013https://hdl.handle.net/1920/8289This dissertation addresses two important issues in cooperative cognitive radio networks: spectrum sensing in physical layer and dynamic resource allocation in MAC layer. The goal of spectrum sensing is to find the vacant spectrum bands opportunistically and have them accumulated in a spectrum pool. In the MAC layer the detected bands are allocated to the Secondary Users (SUs) dynamically to take the best advantage of the temporarily granted resources.107 pagesenCopyright 2013 Akram BaharloueiElectrical engineeringCognitive RadioDynamic resource allocationGame TheoryNash Bargaining SolutionOFDMSpectrum SensingDynamic resource allocation in OFDM-based Cognitive Radio NetworksDissertation
