Optimization Framework for Uplink Video Transmission in HetNets

Abstract : To deal with the explosion of mobile traffic, network operators deploy heterogeneous networks (HetNet), a combination of macro and pico eNodeBs. In this paper, we propose an optimization framework for the study of the optimal performances of HetNet on the uplink. We focus on video traffic because technologies like WebRTC allow mobile users to upload live video streams in cellular networks. Optimization model for uplink is much more complex than for downlink, for which previous works exist. Our model integrates both network management (radio resource allocation, user-cell association, interference management) and video (encoding bit-rate, QoE metrics). We apply our framework on an use case and reveal the complexity of HetNet management due to the interplay between several parameters.
