Adaptive video streaming rate control for HetNet based on interference scenarios

Abstract

The demands for video traffic is increasing over mobile networks which are taking another shape by its heterogeneity. However, the wireless link capacity cannot cope with the traffic demand, this is due to the interference problem which can be considered as the most important challenge in heterogeneous networks. Consequently, it will result in poor service for the quality of video streaming such as the bad quality delivery, service interruption, etc. In this paper, we propose a solution for interference mitigation in the context of heterogeneous networks through power control mechanism, while guaranteeing the Quality of Service of the video streaming. We derive a model for adapting the video bit rate to match the channels achievable bit rate. Our results demonstrate a high satisfaction for video streaming in terms of delay and throughput.
