I have been insisted to "Port RIP On SDN" as my final year project. But my doubt is like when the controller has an intelligence of routing , whys RIP on SDN. Is there any other advantage of using RIP as an application in SDN ? Is this a valid project to proceed ?

I think in SDN you can use link-state routing protocol because in SDN you have information of all nodes in network, but you can use such distributed algorithm between SDN controllers. Frameworks like hyperflow (for more information see HyperFlow: A Distributed Control Pane for OpenFlow paper) use this idea for distributed control pane.

You would need to use the path finding logic of RIP or any other routing protocol on the topology discovered through SDN southbound protocols to find a path for routing traffic. Then you need to insert the rules which reflect this path on the dataplane.
