Joint On-Demand Routing and Spectrum Assignment in Cognitive Radio Networks
— In Cognitive Radio Networks, nodes can work on different frequency bands. Existing routing proposals help nodes select frequency bands without considering the effect of band sw...

CAODV: Routing in mobile ad-hoc cognitive radio networks
This paper deals with the routing in cognitive mobile ad hoc networks. We propose to modify the widely adopted Ad-hoc On-demand Distance Vector (AODV) protocol [1] in order to assu...

On Myopic Sensing for Multi-Channel Opportunistic Access
We consider a multi-channel opportunistic communication system where the states of these channels evolve as independent and statistically identical Markov chains (the Gilbert-Elli...

Optimality of Myopic Sensing in Multi-Channel Opportunistic Access
—We consider opportunistic communications over multiple channels where the state (“good” or “bad”) of each channel evolves as independent and identically distributed Mark...
