Deriving QoE in Systems: From Fundamental Relationships to a QoE-based Service-level Quality Index

, 2020
With Quality of Experience (QoE) research having made significant advances over the years, service and network providers aim at user-centric evaluation of the services provided in their system. The question arises how to derive QoE in systems.

Mobile QoE prediction in the field

Pervasive and Mobile Computing, 2019
Abstract Quality of experience (QoE) models quantify the relationship between user experience and network quality of service. With the exception of a few studies, most research on QoE has been conducted in laboratory conditions. Therefore, in order to validate and develop QoE models for the wild, researchers should carry out large scale field studies.

Secure Live Streaming: Implementing Security in Adaptive Video Streaming via Watermarking Techniques While Preserving Quality

International Journal of Digital Multimedia Broadcasting, Volume 2026, Issue 1, 2026.
The heterogeneity of the network at the edge creates unequal bandwidth availability for clients connected through diverse networks and devices. This variability can lead to bandwidth fluctuations and slow response times, resulting in buffering or degraded streaming performance.

Study on the QoE for VoIP Networks

Journal of Networks, 2014
In recent years, people are recognizing that the quality in VoIP application should be evaluated according to the QoE (Quality of Experience). The main goal of this paper is to analyze the different factors on the impact of voice quality for VoIP networks. Our contributions are thus threefold: First, we establish a new VoIP simulation platform.
