Joint dynamic resource allocation and waveform adaptation in cognitive radio networks
This paper discusses the issue of dynamic resource allocation (DRA) in the context of cognitive radio (CR) networks. We present a general framework adopting generalized transmitte...

Joint Rate Control and Spectrum Allocation under Packet Collision Constraint in Cognitive Radio Networks
Abstract-- We study joint rate control and resource allocation with QoS provisioning that maximizes the total utility of secondary users in cognitive radio networks. We formulate a...

QoS Provisioning for Heterogeneous Services in Cooperative Cognitive Radio Networks
—In this paper, we propose a spectrum allocation framework that jointly considers the Quality-of-Service (QoS) provisioning for heterogeneous secondary Real-Time (RT) and Non-Rea...
