CRP: A Routing Protocol for Cognitive Radio Ad Hoc Networks
Abstract—Cognitive radio (CR) technology enables the opportunistic use of the vacant licensed frequency bands, thereby improving the spectrum utilization. However, the CR operati...

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....

Resource Allocation for Downlink Spectrum Sharing in Cognitive Radio Networks
— We consider a resource allocation problem for spectrum sharing in cognitive radio networks. Specifically, we investigate the joint subchannel, rate and power allocation for se...

On reliable broadcast in a radio network
— We consider the problem of reliable broadcast in an infinite grid (or finite toroidal) radio network under Byzantine and crash-stop failures. We present bounds on the maximum...
