Abstract
Smart and connected vehicles have enabled a series of services and applications in intelligent transportation. Such vehicles introduce a new paradigm that supports the Internet of Vehicles, where content and resource sharing happens dynamically through Vehicle to Everything (V2X) communication. Communication technologies, such as vehicular and cellular networks, are expected to reliably support connections and mobile computing. However, due to challenges related to highly dynamic topologies in urban environments, the feasibility and reliability of vehicular communications in real urban environments have been discussed in recent works. In light of solving the issues that originated from unstable connectivity, we propose an MDP-based connectivity model which estimates link stability for data delivery. Moreover, from analyses, it was evident that the predictability of individual vehicle connectivity directly depends on the repeatability of its connection patterns. Consequently, we propose an availability model which identifies the suitability of connectivity status to determine the vehicles that provide high availability conditioned on their mobility.
