Survey: Routing Protocols in Cognitive Radio Mesh Networks

Abstract-Cognitive radio is the upcoming and promising technology that solves the issue of spectrum allocation by allocating the required space to both primary and secondary users accordingly, without any interference by understanding the environment of the spectrum. In present scenario there is more demand for usage of wireless technology and also for spectrum usage, so a device like cognitive radio could be able to solve all issues and helps for better functioning of these technologies. Routing in cognitive radio is very difficult and a challenging task due to the dissimilarity in channels present and the flow of data. In this paper we have outlined on basic concepts of CRN including its architecture and its functionalities. We have surveyed on some traditional routing protocols in cognitive radio network based on their classification and operation. Our scope of work will make you better understand on operations of various routing protocols and their advantages
