Utility-based power control for peer-to-peer cognitive radio networks with heterogeneous QoS constraints
Transmit-power control is a critical task in cognitive radio (CR) networks. In the present contribution, adherence to hierarchies between primary and secondary users in a peer-to-...

Control Channel Establishment in Cognitive Radio Networks using Channel Hopping
Abstract—In decentralized cognitive radio (CR) networks, enabling the radios to establish a control channel (i.e., “rendezvous” to establish a link) is a challenging problem....
