Transmission Scheduling for Routing Paths in Cognitive Radio Mesh Networks
Nodes in a cognitive radio mesh network may select from a set of available channels to use provided they do not interfere with primary users. This ability can improve overall netwo...

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...

Algorithms for Dynamic Spectrum Access with Learning for Cognitive Radio
We study the problem of dynamic spectrum sensing and access in cognitive radio systems as a partially observed Markov decision process (POMDP). A group of cognitive users cooperati...

Spectrum mobility games
Cognitive radio gives users the ability to switch channels and make use of dynamic spectral opportunities. However, switching channels takes time, and may disrupt the quality of a...
