Over-the-top mobile adaptive video streaming is invariably influenced by volatile network conditions, which can cause playback interruptions (stalling or rebuffering events) and bitrate fluctuations, thereby impairing users’ quality of experience (QoE). Video quality assessment models that can accurately predict users’ QoE under such volatile network conditions are rapidly gaining attention, si...

Real-time multimedia will be among the most important applications in next generation networks. However, efficiently managing the delivery of these applications to guarantee Quality of Experience (QoE) to end-users facing network resources limitation and heterogeneity of networks is a challenge. This paper first explores key requirements to provide QoE assurance for multimedia applications in C...

Playing cooperative games should be fun for everyone involved. Part of having fun in games is being able to perform well, be immersed, and stay engaged [18, 30, 31]. These indicators of experience are part of a game player’s Quality of Experience (QoE). One of the primary causes of QoE degradation in online games is lag, a general term for communication delay and loss due to poor network condit...

Abstract To deliver the best user experience (UX), human-centered design cycle (HCDC) serves as a well-established guideline to application developers. However, it does not yet cover network-specific requirements, which become increasingly crucial, most applications over Internet. The missing network-centric view is provided by Quality of Experience (QoE), could team up with UX towards an impro...

The ROMEO project focuses on the delivery of multiview 3-Dimensional (3D) video enriched with spatial audio on a converged network architecture. Quality of Experience (QoE) modeling plays an important role in several aspects of the overall ROMEO architecture, such as in video compression, multicast tree formation in the P2P overlay, content adaptation and view synthesis. To address various use ...

Recently, Quality of Experience (QoE) of voice service has been paid more attentions because it represents the performance of voice service subjectively perceived by the end users. And speech quality is commonly used to measure the QoE value. In this paper, a speech quality assessment algorithm is proposed for GSM network, aiming to predict and monitor QoE of voice service based on radio link p...

Although the literature on Quality of Experience (QoE) has boomed over the last few years, only a limited number of studies have focused on the relation between objective technical parameters and subjective user-centric indicators of QoE. Building on an overview of the related literature, this paper introduces the use of a software monitoring tool as part of an interdisciplinary approach to QoE...

Cloud computing provides an effective approach to deliver multimedia services to end users with the desired user quality of experience (QoE). However, cloud-based multimedia applications require many of servers and consume huge energy. To reduce energy consumption, a multimedia service provider (MSP) should balance the energy and QoE. In this paper, a theoretic model is developed to explore the...
