Abstract
Vehicular communications is a growing area for communications between vehicle and everything. On the other hand, information-centric networking (ICN) is being recognized as a new paradigm for the future Internet and 5G networks. Content-centric networking (CCN) is a similar approach to ICN. In this paper, we propose an architecture and functional entities for CCN-based vehicle-to-everything (V2X) communications. We concentrate on various V2X communication scenarios and the applicability of CCN in the respective scenarios using proactive caching and optimized routing. We also show that CCN in-network caching can be effective by using the content popularity and the degree of vehicular safety oriented content. In addition, we analyze the performance of the architecture and demonstrate that proactive caching works better than reactive caching.
