Evaluating Video Streaming in Network Architectures for the Internet of Things

In this paper we discuss the experimentation results we obtained from performing video streaming in Internet of Things (IoT) scenarios built on top of Content Centric Networking (CCN) architecture. More precisely, we used the Dynamic Adaptive Streaming over HTTP (DASH) mechanism to split videos into multiple pieces, also offering multiple bit-rates. Such pieces are then streamed by a DASH client from a typical HTTP server through a CCN network. HTTP/CCN adapters are used to translate the HTTP requests to CCN interests and HTTP responses to CCN content objects. The results are promising, the experiment demonstrated that CCN can fit into IoT environments and that its integrated caching mechanisms will highly reduce the necessary time to retrieve content, specifically streamed video, therefore increasing network efficiency.
