A quorum-based framework for establishing control channels in dynamic spectrum access networks
Establishing a control channel for medium access control is a challenging problem in multi-channel and dynamic spectrum access (DSA) networks. In the design of multi-channel MAC p...

Dynamic Spectrum Access Using a Network Coded Cognitive Control Channel
In this paper we propose a Dynamic Spectrum Access scheme which allows the users to opportunistically and efficiently access the channels available for communications. It addresses...

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....

A Framework for Dynamic Spectrum Sharing Between Cognitive Radios
— We consider a cognitive radio system like the future 802.22 networks where license-exempt service providers (SPs) will share a fixed spectrum in a non-interference basis to ea...

Joint rate and power allocation for cognitive radios in dynamic spectrum access environment
Abstract--We investigate the dynamic spectrum sharing problem among primary and secondary users in a cognitive radio network. We consider the scenario where primary users exhibit o...
