TL;DR: The concepts and ideas cited in this paper mainly refer to the Quality of Experience of multimedia communication systems, but may be helpful also for other areas where QoE is an issue, and the document will not reflect the opinion of each individual person at all points.
Journal ArticleDOI
Challenges of QoE management for cloud applications
TL;DR: Technical challenges emerging from shifting services to the cloud are discussed, as well as how this shift impacts QoE andQoE management, with a particular focus on multimedia cloud applications.
Journal ArticleDOI
QoE beyond the MOS: an in-depth look at QoE via better metrics and their relation to MOS
TL;DR: The limitations of MOS are put forward, other statistical tools that provide a much more comprehensive view of how quality is perceived by the users are presented, and the results of several subjective studies with these tools are analyzed.
Journal ArticleDOI
Definition of QoE Fairness in Shared Systems
TL;DR: It is argued that neither QoS fairness nor Jain’s fairness index meet all of the desirable QoE-relevant Properties, which are met by the proposed inline-formula, so the proposed index may be used to compareQoE fairness across systems and applications, thus serving as a benchmark for QOE management mechanisms and system optimization.
Journal ArticleDOI
A Survey of Emerging Concepts and Challenges for QoE Management of Multimedia Services
TL;DR: QoE management is addressed in the context of ongoing developments, such as the move to softwarized networks, the exploitation of big data analytics and machine learning, and the steady rise of new and immersive services.
