This paper presents a novel context-aware methodology for modelling and measuring user-perceived quality of experience (QoE) over time. In particular, we create a context-aware model for QoE modelling and measurement using dynamic Bayesian networks (DBN) and a context-aware state-space approach. The proposed model is then used to infer and determine users’ QoE in a sequential manner. We perform...

This paper outlines ongoing work that responds to the need to provide network operator, equipment manufacturer and service provider organisations with usable data about the Quality of Experience (QoE) with real-time multimedia services. The main requirements for QoE data are introduced and a technique for making QoE data available in industry is summarised. Example guidelines are provided in ad...

The growth of emerging multimedia applications with different quality requirements has made the objective network QoS (NQoS) to be commonly considered as an inadequate metric for quality assessment in telecommunication services, being the quality of experience (QoE) concept the most predominant alternative. However, most QoE-related research studies are service-specific, not easily expandable t...

Researching a Future Internet capable of overcoming the current Internet limitations is a strategic investment. In this respect, this paper presents some concepts that can contribute to provide some guidelines to overcome the above-mentioned limitations. In the authors' vision, a key Future Internet target is to allow applications to transparently, efficiently and flexibly exploit the available...

The increasing popularity of wireless and cellular networks multimedia traffic among the consumers has raised new demands for investigation of their underlying Quality of Service (QoS) and Quality of experience (QoE) requirements. In this work, we carry out an application-based analysis of such requirements. Using this approach, we can properly take into account the heterogeneous nature of the ...

In the present time to satisfy the increasing requirement of wireless technology by using scare Resource of bandwidth is a biggest challenge for Researchers, in this time WiMAX (Worldwide Inter-operability for Microwave Access) appeared as better solution to fulfill that requirement. WiMAX provides faster internet connectivity in Urban Areas as well as remote areas also where to deploy the DSL ...

Early identification of relevant factors that influence students' experiences is vitally important to the educational process since they play an important role in learning outcomes. The purpose of this study is to determine underlying constructs that predict high school students’ subjective experience and quality expectations during asynchronous and synchronous distance education activities, in...

Actually, wealthy network services such as Internet protocol television (IPTV) and Voice over IP (VoIP) are expected to become more pervasive over the Next Generation Network (NGN). In order to serve this purpose, the quality of these services should be evaluated subjectively by users. This is referred to as the quality of experience (QoE). However, there are many issues that may impact user’s ...
