Network Extensions to Support Robust Secured and Efficient Connectivity Services for V2X Scenario

This paper introduces enhanced network control and management methods for Over-the-Air Vehicular Software Updates (OTAVSUs), emphasizing robust connectivity, security assurance, and computational efficiency. Firstly, we present a robust Vehicle-to-Everything (V2X) connectivity framework to guarantee prompt OTA-VSU delivery. Our novel Location-Aware Software-Defined Networking (SDN) Controller and Service Orchestrator allows network management and service delivery across contemporary data centers and communication networks. This advanced approach synergizes software-defined networking with intelligent service orchestration, fostering a highly adaptive and efficient networking ecosystem. The paper also details security enhancement strategies for OTA-VSUs. It encompasses the deployment of sophisticated security measures, proactive identification and mitigation of potential security threats, and the creation of virtual security functions. A key innovation is our Security as a Service component, which operationalizes security service level agreements into actionable, networkspecific rules. Finally, the paper advocates for the adoption of computationally efficient methodologies to expedite OTA-VSU data processing. This includes integrating Multi-Access Edge Computing (MEC) with European Telecommunications Standards Institute (ETSI) TeraFlowSDN (TFS) network control system. A novel feature is our MEC Bandwidth Management (BWM) service, crucial in managing bandwidth allocation and prioritization for MEC applications. This mechanism allows MEC applications to precisely define their bandwidth needs, ensuring seamless OTA-VSU update transmissions.
