Profit Optimization for Multiuser Video Transmission over Mobile Networks

Abstract

Abstract With the increasing demand for high quality mobile video, how to receive higher quality video through mobile network with lower payment is a becoming an emerging problem. Existing approaches for Dynamic Adaptive Streaming over HTTP (DASH) face tremendous challenges when applying to video streaming in devices with different resolutions. In this paper, we propose a comprehensive profit optimization model with consideration of the cost of Content Provider, traffic payment, QoE factors and the relationship between device resolution and video quality. For ensuring the optimal profit of Content Provider and End Users at same time, we formulate both of their profit as a hybrid-objective optimization model. By solving the model, the optimum bitrates and the resulting profit can be obtained through our proposed algorithm. The simulation results demonstrate that the proposed method increases the average profit of End Users in 10%-15% compared with existing approaches.
