Abstract
Providing robust content delivery service, such as Video on Demand, with efficient wireless resource usage is important for mobile users. To achieve this, we have proposed a proactive content caching scheme utilizing transportation systems (e.g., train.) Because our previous prototype is immature and has a scalability issue, in this paper, we introduce efficient transmission mechanism of Interest messages in order to improve throughput efficiency in mobile NDN. We develop two prototypes based on HTTP and NDN and then evaluate prototype performance by performing larger-scale field experiments on actual commercial railroad line. Evaluations conclude that our system can achieve high efficient content transfer and fully utilize wireless network bandwidth. Therefore, our system can provide high-quality video streaming for up to 50 users simultaneously.
