User-aware adaptive transmission scheme for delivering multimedia traffic in content centric network

With the increasing flooding of multimedia information traffic, it is clearly that the content is bound to play a more and more significant role in the future multimedia Internet. Content Centric Networking(CCN), as a typical content-oriented architecture, is designed for efficient content delivery. Therefore, CCN mechanism is extremely appropriate for the explosive content items and well suited to the multimedia Internet. However, future multimedia Internet should not only focus on the diverse content items, but also provide personalized services to meet users´ specific demands. In this paper, we propose a user-aware adaptive transmission scheme(UAAT) for content centric multimedia internet, which can allocate appropriate bandwidth and select the best forwarding interface dynamically for requests by differentiating varieties of user´s level. We evaluate the UAAT scheme using ndnSIM and the results indicate that the proposed scheme can utilize available bandwidth effectively and work well on level-based priority service.
