A Fog Networking Solution for DASH-based Video Streaming

The delivery of video content over the internet has surged and internet video consumption has taken over the top spot in bandwidth usage. With this boom and the improvement in the quality of videos, the need for adequate delivery and data compression pushed the world for technological advances to sustain that usage. Dynamic Adaptive Streaming over HTTP (DASH) emerged as a leading choice and the standard for the delivery of video segments that are in line and conformable to the network conditions of the end users. The cloud was able to facilitate streaming by offering the resources and the storage when needed. Nevertheless, there were still problems that needed to be addressed such as latency, distribution and energy consumption. Fog computing is suggested as the solution for these problems as it can be combined with DASH to provide a more reliable and seamless stream. The combination aims to distribute the video segments over the fog nodes, allowing for a faster delivery and an efficient system. This is evaluated through a series of simulation that measure various aspects of the system. The results illustrate the feasibility and the potential of the proposed solutions.
