OpenFlow based Topology Discovery Service in Software Defined Vehicular Networks : limitations and future approaches
Résumé
This paper presents our ongoing work towards the definition of an effective topology discovery service for SDN based hybrid vehicular networks. The main contributions of this paper are threefold: (1) an analysis of the main limitations of the "de facto" topology discovery service when applied to vehicular networks; (2) a quantitative assessment of its traffic overhead and the required computing resources at the controller to show the scalability issues that it raises; and (3) an insight into our design principles for an effective topology discovery service for SDN-based hybrid vehicular networks.
