A cognitive spectrum management framework

With the broadening followers of wireless communication technology current technology for radio or wireless network is required to be enhanced in terms of managing the present provided resources. There is a committing encouraging technology that can enhance the usage of wireless spectrum. The basic approach for this is to combine hardware as well as software framework to built a architecture that meets the requirements of the spectrum and comply with the enforcements of spectrum policy rule. In this paper, we propose a rational supervisory technique for cognitive radio called as cognitive spectrum management framework. This framework is able to deal with various environmental circumstances. It assigns channels, rearranges radio distribution parameters, assures fidelity of three main layers : Interface layer, decision layer and enforcement layer. Cognitive spectrum management technique is implemented on a USRP N210 that is connected to MATLAB. Spectrum Sensing and physical parameters are collected with the help of network sniffer and later optimization procedure handles the behavior of transmission.
