Internet television (IPTV) is rapidly gaining popularity and is being widely deployed in content delivery networks on the Internet. In order to pro-actively deliver optimum user Quality of Experience (QoE) for IPTV, service providers need to identify network bottlenecks in real-time. In this paper, we develop psycho-acousticvisual models that can predict user QoE of multimedia applications in r...

This paper introduces a cognitive radio scheme based on quality of experience (QoE). QoE involves the mobile end user’s preferences. Considering QoE can lead to an improved cognitive radio resource management strategy. The cognitive radio scheme aims to manage the traffic flow in dynamic systems; it is a new way of thinking about dynamic resource management in cellular systems. The Use of the c...

When delivering multimedia services over Internet, different media types are impacted by resource limitations in a different way. While an interactive audio service calls for low-latency communication, video streams should be routed over network paths with sufficient capacity. However, in current networks flows towards the same destination follow the same path, which may lead to a suboptimal re...

For improving the system performance of mobile Internet, how to provide the Quality of Experience (QoE) guarantee is an important factor. First, based on artificial neural network and adaptive cross-layer perceptron, we studied the cloudassisted QoE guarantee mechanism. Then, according to the power, we divided the distance and perceptron layers of mobile Internet and cloud into three levels. We...

Quality of Experience (QoE) is a relatively new concept which represents a way of measuring user satisfaction in the use of a certain kind of service. This work investigates issues related to the QoE in manipulating 3D scenes on mobile devices, by focusing on scenarios based on the remote visualization paradigm where a remote server is in charge of computing a flow of compressed images to be de...

One of the most interesting applications of single–sided Quality of Experience (QoE) metrics is their use in improving the quality of the service, as perceived by the user. This can be done either at the application level – by for example changing the encoding in use, or the level of error correction applied – or at the network level, for instance by choosing a different DiffServ marking strate...

To provide customer-satisfied video streaming services over 3G, network services providers turn to measure the video quality in term of quality of experience (QoE) rather than quality of service (QOS). In formal QoE definitions for video streaming services over 3G, QoE is either regarded as the average user opinion from the subjective point of view or combination of some technical parameters fr...

Preface Crowdsourcing is a popular approach that outsources tasks via the Internet to a large number of users. Commercial crowdsourcing platforms provide a global pool of users employed for performing short and simple online tasks. For quality assessment of multimedia services and applications, crowdsourcing enables new possibilities by moving the subjective test into the crowd resulting in lar...

Cooperative Wireless Networks (CWN) have become an attractive alternative for providing ubiquitous and inexpensive connectivity to mobile users. In a CWN, some hot-spot areas may experience the problem of sporadic congestions. The appearance of this localized congestion adversely impacts the network performance in terms of effective throughput, leading to a Quality of User Experience (QoE) degr...
