#Rdio for mac mac
With our categorization, an easy and concise view of underlying models for development of a CR MAC protocol is provided.Īs modern large-scale wireless networks grow in size, complexity and variety, the change in networks is not just terms of scale but also in the emergence of newer types of communication networks such as cognitive radio (CR) networks, ad-hoc, peer-to-peer (P2P), multiagent, wireless sensors, internet of Things (IoT), social and cloud-based networks. We group existing approaches for development of CR MAC protocols and classify them into different categories and provide performance analysis and comparison of different protocols. A detailed analysis on CR MAC protocols form part of this paper. This paper surveys the state of the art on tools, technologies and taxonomy of complex self-organizing CR networks.
Since inception of CR technology, several MAC protocols have been designed and developed. Moreover, CR nodes should intelligently coordinate their access between different cognitive radios to avoid collisions on the available spectrum channels and to vacate the channel for the licensed user in timely manner. CR devices must be capable of exploiting spectrum opportunities and exchanging control information over a control channel. Complex self-organizing cognitive radio (CR) networks serve as a framework for accessing the spectrum allocation dynamically where the vacant channels can be used by CR nodes opportunistically.
