Maximizing Throughput of Cognitive Radio Networks with Limited Primary Users' Cooperation
— We consider a point-to-multipoint cognitive radio network that shares a set of channels with a primary network. Within the cognitive radio network, a base station (BS) controls...

Primary User Enters the Game: Performance of Dynamic Spectrum Leasing in Cognitive Radio Networks
Dynamic spectrum leasing (DSL) is one of the schemes proposed for dynamic spectrum sharing (DSS) in cognitive radio networks. In DSL, spectrum owners, denoted as primary users, dyn...
