A Study on Semi-Structure Routing mechanism in Cognitive Radio Networks
نویسنده
چکیده
Cognitive Radio Networks (CRNs) is mainly resulting to trim down the drawbacks of current unbalanced and inefficient spectrum utilization on licensed spectrum bands. Routing is one of the most important and fundamental mechanism in the cognitive radio networks. To overcome the limitations of existing routing mechanism, many researchers develop a routing framework which is based on Semi Structure Routing (SSR). Semi Structure Routing framework incorporates power control strategy. By adopting the Forwarding Zone concept, efficiency of spectrum utilization is improved. Hence, Semi Structure Routing enhances the spectrum utilization. Hence the overall performance of Semi Structure Routing can be guaranteed. This mechanism can also avoid the high-cost complex and tortuous routes from sources to destinations. This paper gives review of some routing mechanisms in cognitive radio networks which improves and guarantees the performance of network. Keywords— Cognitive Radio Networks, SSR, Forwarding Zone, tortuous routes, routing framework.
