Abstract:
Video streaming is among the most popular applications for mobile network. DASH-based adaptive video streaming is has been deployed to provide better video steaming Quality of Experience (QoE). On the other hand, the emerging fog computing and networking paradigm enables better system performance of latency sensitive applications. In this talk, system design challenges and solutions in fog-based computing/communications/caching systems will be discussed. We proposed an integrated framework of MPEG-DASH SAND service and hierarchical Fog computing architecture to provide better multimedia QoE. The proposed multimedia fog architecture along with the proposed resource allocation mechanisms optimize user QoE in fog-based video streaming services. In addition, I will share my personal experiences in academic research as well as industrial standard activities in fog computing and networking architecture.
