The ICT industry and services are on the verge of substituting quality of service and utility functions with quality of experience, QoE. While intuitive, QoE, has eluded the research community. QoE takes into account what the user is experiencing with new products and services. Once this information is collected, it becomes an input in the development of the new product or new service. But how ...

The measurement of Quality of Experience is largely assessed using the Mean Opinion Score (MOS) that has been defined in telecommunication domain. It is known that MOS measurement focuses on system influencing factors, and strives to filter-out human, contextual and content factors. However, the emerging conceptualization of QoE gives attention to non-functional factors. These factors are known...

Real-time multimedia will be among the most important applications in next generation mobile networks. However, the efficient delivery of these applications to guarantee Quality of Experience (QoE) to fixed and mobile users in multimedia-aware networks is still a research challenge. This paper proposes new approaches to keep voice and video applications with an acceptable quality level in mobil...

Quality of Experience (QoE) is one of the major aspects that service providers focus on during development of their services. However QoE elements that are meant to increase user satisfaction are sometimes contradicting with Quality of Service (QoS) or Quality of Protection (QoP) factors. In order to balance the QoE to QoS or QoP values ratio we propose a method that takes into account various ...

This paper presents a novel authoring framework for Quality of Experience (QoE) aware Adaptive Hypermedia Systems. It extends the LAOS authoring model in order to consider delivery performance issues. The paper formalises and exemplifies the newly proposed QoE extensions for the LAOS Adaptation and Presentation Models that include QoE Characteristics and QoE Rules layers.

User perception of a networking service is usually very different from the operators’ understanding of service usability. Quality of Experience (QoE) metrics are supposed to describe the service from the end-users’ point of view – although QoE is hard to measure for mass services. Collection and analysis of QoS and SLS (Service Level Specification) properties of networking services are daily ta...

The paper presents selected issues on benchmarking the Quality of Experience (QoE) for video streaming and multimedia P2P search services being investigated in the VIFP NoE CONTENT Content Networks and Services for Home Users under participation the Department of Telecommunications (AGH University of Science and Technology Krakow). The first section of the paper presents the general approach us...

This report documents the program and the outcomes of Dagstuhl Seminar 12181 “Quality of Experience: From User Perception to Instrumental Metrics”. As follow-up of the Dagstuhl Seminar 09192 “From Quality of Service to Quality of Experience", it focused on the further development of an agreed definition of the term Quality of Experience (QoE) in collaboration with the COST Action IC1003 “Qualin...
