Model Driven Architecture for Decentralized Software Defined VANETs

Vehicular Adhoc Networks (VANETs) are considered as a breakthrough technology in providing robust Vehicular communication that guarantees Road safety and offer interactive set of applications. VANET faces certain orchestration and management challenges. Recently, the notion of Centralization of VANET is gaining importance. In this regard SDN (Software defined Network) is integrated with VANET to achieve management goals. SDN renders existing VANET architecture to provide centralized control. Yet for Large-scale VANET, SDN approach does not outperform due to SPOF (single point of failure) in SDN. We have proposed decentralized architectural solution that scales out overall network intelligence into respective local controllers that result in unprecedented elasticity and resource availability. To make this approach operational no standard Architectural approach yet exists. An emerging Model Driven Architecture approach is used that simplifies VANET development using abstract models. It only subdues VANET rigidity but also comply with SDN principals. This system is implemented in VEINS framework. Results demonstrate its efficacy for large scale VANET.
