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.

The future work has to be done in fallback mechanism
which would be a key feature that must be provided to
apply the SDN concept into mobile wireless scenarios
since the nodes are always unstable. Transmission power
control should be made as a provision in the services
which are offered by Software-Defined VANET. In case
of partial SDN controller connectivity loss, where only a
subset of mobile nodes loses communication to the
controller, remaining nodes should be able to continue
functioning.
