A vehicular AD-HOC Network (VANET) is a specific case of the wireless multi-hop network with the constraint of fast topology swaps due to its high node mobility. VANET has acquired great importance for its fast, highly growing technology and its requirement provisions in intelligent transportation systems (ITS) and vehicular social networks (VSN).
To assured secured communication, VANET must implement an authentication protocol to endure the attacks and preserve some privacy policies. SDN can couple the advanced claims of VANETs features which greatly include,
• High throughput
• High mobility
• Heterogeneity
• Scalability
• Low communication Latency
The benefits of SDN-enabled VANET provide multiple stages such as,
• Rapid network configuration
• Minimizing service latency
• Improving user experience by efficient resource utilization
• Resistance to inherited attacks of SDN or VANETs.
VANET was projected to provide vehicle safety, comfortability, reliability and security while driving. Many vehicular networking applications range from safety-related ones to providing convenience to passengers. VANET consists of two protocols, namely,
• Topology-based routing protocol
• Position-based routing Protocol.
The most commonly used vehicles in VANETs can communicate in the same nodes in mobile ad-hoc networks. Here, communication in VANET can be broadly classified into two types, namely:
• vehicle-to-vehicle (V2V)
• vehicle-to-infrastructure (V2I).
The specific parameters that take place in VANET, such as,
• Network delay
• Quality of Services
• Access control
• Routing reliability
• Security in data communication.
• Traffic control
• Collision avoidance
• Free parking search
• Emergency warning
• Lane change assistance
• Automatic Accident Notification
• Traffic Notation System Driver Assistance.
• Attacks on privacy
• Attacks on non-repudiation
• Attacks on confidentiality
• Attacks on data trust
• Attacks on Availability
• Attacks on Authentication/Identification.
