Abstract
Intelligent transportation systems and connected vehicles, by utilization of new facilities and technologies, have a significant role in improving the quality of today’s transportation. A wide range of applications can be defined in a vehicular network that each one has its own requirements. Compared to other wireless networks, vehicular networks face particular challenges due to the continuous and high-speed movement of vehicles. Concerning the characteristics of content-centric networking (CCN), it has the potential to deal with many of these challenges. In this paper, we modify the basic model of the CCN with the aim of supporting many types of application including safety and non-safety. The applications with pull and push behaviors are both considered in the design process. A new concept of shared-content among different applications is introduced and also taken into account in the presented model. To achieve these goals, the basic content retrieval mechanism has been expanded. The simulation results indicate that the new model has good performance in terms of throughput and content retrieval time.
