Reactive Routing for Mobile Cognitive Radio Ad Hoc Networks

Although more than a decade has passed from the proposal of the Cognitive Radio paradigm, in these years the research has mainly focused on physical and medium access issues, and few recent works focused on the problem of routing in cognitive networks. This paper addresses such a problem by evaluating the feasibility of reactive routing for mobile cognitive radio ad hoc networks. More specifically, the authors design a reactive routing protocol for the considered scenario able to achieve three goals: to avoid interferences to primary users during both route formation and data forwarding; to perform a joint path and channel selection at each forwarder; to take advantage of the availability of multiple channels to improve the overall performance.
