An Intelligent Framework for Vehicular Ad-hoc Networks using SDN Architecture

Abstract

-Vehicular Ad Hoc Network (VANET) is one of the rapid growing areas in the domain of networking technologies that offer various facilities like road safety, providing information about the traffic conditions, weather forecast conditions and events like accident happened on roadside. At present, VANET architecture has not been built with vendor independence and flexibility to be programmable directly without affecting the forwarding operations of data plane. In this paper, the importance of Software Defined Networking (SDN) in VANETs and its deployment using OpenFlow protocol in VANET architecture are discussed. A novel framework is provided for SDN to be employed over VANETs for the future enhancement of vehicular ad-hoc networks.
