Toward a Scalable Software-Defined Vehicular Network

There has been a recent effort from both the academia and the industry to improve the communication management structure of vehicular networks to support multiple services and applications. To this end, software-defined networking has been used together with vehicular ad hoc networks to provide greater flexibility and programming capabilities for more dynamic scenarios. With this in mind, we build upon an existing hierarchical solution for software-defined vehicular networks to deal with the case when there are issues in the communication with the central SDN controller, allowing the vehicles to self-configure to maintain an active infrastructure. Simulation results showed out solution outperforms existing solutions regarding delivery ratio, and throughput, while keeping the communication overhead extremely low, making it suitable for large-scale networks.
