Cognitive networks are capable of learning and reasoning. They can dynamically adapt to varying network conditions in order to optimize end-to-end performance and utilize network resources efficiently. This paper proposes a cognitive network routing scheme that includes a context information collection entity,a route manager entity,a route reconfiguration entity,and reasoning and learning entity.
