A Real World Information-Centric Connected Vehicle Testbed Supporting ETSI ITS-G5

Inter-Vehicle Communication will play an important role in upcoming Intelligent Transportation Systems (ITS). Vehicles are equipped with communication units, able to offer and share information with other cars, infrastructure components or cloud servers. In recent years, researchers in academia and industry worked towards ITS standards to tackle the challenges set by connected vehicle environments such as high latency or communication failures. However, the host-centric communication model of today's networks complicates the exchange of information, especially in vehicle-to-infrastructure (V2I) and vehicle-to-cloud (V2C) communication. The Information-Centric Networking (ICN) paradigm is a promising candidate to solve the challenges set by connected vehicles. Addressing data by name instead of the location, and the resulting capabilities such as in-network caching, make it a good fit for scenarios which are characterized by a high degree of mobility. In this paper, we propose an architectural concept in which ICN and the inter-vehicle communication system ETSI ITS-G5 (based on IEEE 802.11p) coexist and complement each other. Based on the OpenC2X open source platform, we introduce a prototype implementation and verified the prototype within a real world testbed.
