Abstract

Software-Defined Networking (SDN) enabled
Vehicular Ad-hoc Networks (VANETs) are a new paradigm for
vehicular communication that leverages the benefits of SDN to
improve the efficiency, reliability, and security of VANETs. In
an SDN-based VANET, the traditional centralized control
plane architecture is replaced by a SDN controller that manages
the network's routing decisions. The controller has a global
view of the network topology and can dynamically adjust the
routing paths based on changing traffic conditions,
environmental factors. While SDN enabled VANETs offer
many benefits, there are also several challenges. Security is a
critical concern in SDN enabled VANET architectures must
address such as authentication, access control, and data privacy.
Therefore, the researcher presents authentication approach to
solve the challenges. However, the authentication framework
still has challenges in privacy, security, cost. Therefore, in this
paper we summarize the existing authentication scheme to
determine the limitation and the future direction.
