Comparative Study of Adaptive Streaming Techniques in LTE Networks Using QoE Metrics

The use of adaptive transmission techniques through HTTP for the reproduction of video services is becoming more and more popular. Currently, there are problems of interoperability due to the large number of devices with different characteristics, which also used different techniques of adaptive transmission. Therefore, telecommunications service providers are looking for alternatives that allow them to support all this diversity of devices and technologies, in order to offer their users higher quality services. In this paper, we present a comparative performance evaluation of the main adaptive streaming techniques for Live Video Streaming services using QoE (Quality of Experience) as the key performance indicator. The study is carried out in an emulated LTE (Long Term Evolution) network composed by real devices (video server and client) interacting with an NS-3 simulated LTE network. We show for the constructed emulation scenario, the technology that presents the best performance in terms of delays and user mobility.
