Rodolfo W. L. Coutinho, Azzedine Boukerche, Xiangshen Yu · 2018
Efficient content delivery in vehicular networks will play a fundamental role in empowering envisioned vehicular and smart transportation applications. However, the peculiar characteristics of vehicular networks (e.g., high mobility, dynamic network topologies, and intermittent connectivity), as well as the string QoS requirements of the applications, challenge the design of efficient solutions for content delivery in these environments. In this paper, we discuss the recent trend of applying the information-centric networking (ICN) paradigm for content delivery in vehicular networks. By doing so, we highlight the potentials of this novel paradigm and how it can deal with the severe challenges of vehicular networks. Besides, we point out the limitations of current ICN implementations when applied in vehicular networks. Furthermore, we discuss the new challenges that need be tackled in ICN-based vehicular networks, the proposed solutions encountered in the literature and, based on that, we provide some guidelines for the design of new solutions and some future research directions.
