Impact of Network Scenarios on Quality of Experience using TRIANGLE Testbed

摘要

The TRIANGLE project aims at building a 5G testing framework that can allow end-to-end Quality of Experience (QoE) evaluation for new mobile applications and devices. An important task in building such a testbed is the definition of network scenarios which should cover as many user conditions as possible. This paper presents the general testbed framework and the identified network scenarios. An analysis of the number of iterations needed to achieve stable results has also been carried out and shows that the required iterations depend on the network scenario and the traffic profile. A case study of a content streaming application (Exoplayer) with focus on the user experience domain is presented. The measurement results show that the network scenario has significant impact on the measured Key Performance Indicators (KPIs), which sheds some light on how propagation channel models and radio resources will influence the overall application/service performance.
