Content-centric networking for telematics services

As the wireless communication and the vehicular networking technologies have rapidly developed, researches on telematics have been carried out extensively. Even though most of telematics services are delivered via cellular network between a base station and a vehicle in the current stage, the advent of DSRC/WAVE standard in vehicular communications will change the paradigm of telematics applications and create a new demand for telematics services. However, DSRC/WAVE still utilizes TCP/IP protocol which is considered inappropriate for dynamic network environment like vehicular networks. To resolve the inherent limitations of TCP/IP protocol, we propose to adopt Content-Centric Networking (CCN) for DSRC/WAVE protocol stack and suggest its system architecture, naming structure and the naming examples for telematics services. We also provide a proper data request cycle and the practicality of CCN caching mechanism based on the understanding of current telematics services.
