Cognitive Radio is a promising technology to maximize spectrum efficiency that can be applied to dense residential infrastructure and heterogeneous networks. This paper proposes a Software Defined Networking (SDN) system model for coordinated adaptive spectrum sharing and interference management; the SDN system model leverages the fact that Primary User (PU) network traffic is bursty with an optimal reinforcement learning scheme and takes into account network topology information and data rate requirements of active flows. The scheme learns PU traffic, and as a result, it optimizes spectrum brokerage to the active flows for QoS provisioning and performs interference mitigation.
