Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Cognitive Radio (CR) is a promising approach to overcome the spectrum crunch faced by today's enterprise and residential WiFi (IEEE 802.11) due to rapid growth of wireless devices and traffic load. Hover, the expected high-density CR Networks (CRN) will suffer from similar problems as  see today with WiFi, i.e. any uncoordinated spectrum access will inevitably result in interference beten Secondary Users and hence in a low spectral efficiency.   take advantages of the ideas of Software-Defined Networking (SDN) and cloud computing technology to manage interference in CRN deployments in residential areas. Specifically,  propose a flexible SDN-based CR architecture where a cloud-based centralized controller, the Spectrum Broker (SB), takes control over the spectrum assignment for the CR Base Stations (CR-BS). To enable that, the CR-BSs under control report aggregated wireless statistics to the SB. Moreover, by configuring proper rules in OpenFlow-enabled CR-BSs, the SB controller can get up-to-date information about the network traffic condition in the CRN. With this information the SB can perform a very fine-grained topology-, traffic- and channel-aware spectrum allocation. Our architecture, as ll as the proposed spectrum allocation scheme, re analyzed by means of emulation within Mininet. Results demonstrate a gain of up to 5x as compared to a static spectrum allocation scheme.
