A Two-Tier Market for Decentralized Dynamic Spectrum Access in Cognitive Radio Networks
Market mechanisms have been exploited as important means for spectrum acquisition and access in cognitive radio networks. In this paper, we propose a two-tier market for decentrali...

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...

Optimal Power Allocation for Cognitive Radio Under Primary User's Outage Loss Constraint
In this paper, we consider a secondary link sharing the spectrum with a primary link in a fading cognitive radio (CR) network. Instead of applying the conventional interference pow...

Game Theoretic Rate Adaptation for Spectrum-Overlay Cognitive Radio Networks
— We consider the issue of fair share of the spectrum opportunity for the case of spectrum-overlay cognitive radio networks. Owing to the decentralized nature of the network, we ...
