C-V2X resource deployment architecture based on moving network convoys

A reliable and all-pervading information-sharing mechanism between traffic participants and infrastructure systems, widely termed V2X communication, is crucial to realize the goals of future cooperative intelligent transportation systems – that of improving traffic safety and efficiency. The need to maintain high reliability and availability amidst a permanently changing network topology caused by the moving vehicles translates into an increased demand for network management infrastructure and radio resources. Such capital-intensive demands can act as significant deterrents in the quest for a rapid large-scale deployment of V2X technologies. With the goal to reduce the demand for fixed infrastructure and radio resources, we propose an alternate network deployment architecture based on the concept of moving network convoys, deploy it in a distributed C-ITS simulation environment, and provide a quantitative assessment of the potential benefits in comparison to conventional network deployment architectures.
