With 57 % of the world's population living in urban areas, traffic congestion has become a critical issue, driving the demand for smarter and more efficient transportation systems. Road safety is a key factor in this demand, alongside concerns about the sustainability of future mobility. To address these challenges, transportation systems can be modeled as Vehicular Ad-hoc Networks (VANETs), where vehicles act as nodes with communication capabilities, interacting with each other and roadside infrastructure. This infrastructure collects vehicle-generated data and transmits it to edge computing devices. In this context, Software-Defined Networking (SDN) offers a way to efficiently manage and control the network for flexible traffic flow. Building on the existing integration of SDN and Vehicular Ad Hoc Networks (VANETs), this paper introduces a novel framework for Software-Defined Vehicular Networks (SDVN). Specifically, we propose a robust framework that addresses the dynamic mobility of microservices in vehicular networks. Vehicles are treated as service consumers, supporting diverse applications ranging from road safety to infotainment, each with distinct requirements. To complement this framework, we develop a minimalistic mobility strategy designed to optimize service placement and maintain network efficiency. The framework and strategy are evaluated in an emulated environment, demonstrating their potential to enhance service availability and support future network optimizations.
