Vehicular ad hoc networks (VANETs) are one of the key technologies used for developing an Intelligent Transportation System (ITS). They are expected to provide seamless network connectivity to moving vehicles while supporting various services for effective transportation medium. There have been a large number of new technological integrations in VANETs for achieving this objective. Software-Defined Networking (SDN) is also one of the key technologies that is being used for resolving numerous issues of VANETs. Here, we have proposed a smart communication system based on software-defined vehicular networks that will enable vehicles moving at high speed on express highways to avail multiple services to help them commute effortlessly through the expressway. The proposed system provides a captive network for every vehicle that is moving along the expressway that will assist them in moving at high speeds by providing periodic status messages about the road conditions. The proposed communication model uses a two-level hierarchy where Road Side Unit-based controllers are at a lower level that are used to distribute the load of centralized SDN controller that constitutes the upper layer of the model. The lower level controllers work under the assistance of centralized controller only and due to their distributed structure are unable to take decisions on their own. This centralized network architecture provides control of the whole network by providing various services to vehicles. The chapter also discusses a case study that can open the way towards development of the proposed data communication system to support ITS services.
