Performance Study of Adaptive Video Streaming in an Interference Scenario of Femto-Macro Cell Networks

Abstract

Abstract:The demand for video traffic is increasing over mobile networks that 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 that 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 channel's achievable bit rate. Our results demonstrate a high satisfaction for video streaming in terms of delay and throughput.

Mitigating the Impact of Cross-Tier Interference on Quality in Heterogeneous Cellular Networks

“…The introduction of heterogeneous LTE-A networks enabled coping with increasing number of mobile broadband data subscribers and bandwidth-intensive services competing for restricted radio resources [1]. As discussed in [2], the wireless capacity has increased around one million times over the last 50 years due to three reasons: better transmitter/receiver performance, greater bandwidth, and greater number of cells.…”
