This paper concerns the applicability of reputations systems for assessing Quality of Experience (QoE) for web services in Future Internet. Reputation systems provide mechanisms to manage subjective opinions in societies and yield general scoring of a particular behavior. Thus, they are likely to become an important ingredient of Future Internet. Parameters being under evaluation by reputation ...

With the coming of 5G network era, Quality Experience (QoE), which is used to describe experience quality customers in Direct Connect (DC) network, critical operators and hence has been widely studied. The existing evaluation method for QoE unable dynamically adjust parameters so there will be deviations reflect real when complaint events occur. In this paper, a novel progressive model products...

A key factor in designing 3D systems is to understand how different visual cues and distortions affect the perceptual quality of 3D video. The ultimate way to assess video quality is through subjective tests. However, subjective evaluation is time consuming, expensive, and in most cases not even possible. An alternative solution is objective quality metrics, which attempt to model the Human Vis...

One of the biggest problems of the IPTV providers is to offer enough quality of experience (QoE) to their customers. The minimum bandwidth in the access network required to provide IPTV services, jointly with the necessity to guarantee the QoE to the customers, creates the need for new type of algorithms to satisfy the network requirements. Apart from the parameters that depend on the applicati...

applications such as video streaming grow in importance and popularity, addressing user utility function for these multi-layered multimedia applications in NUM formulation becomes vital. In this paper, we propose a new multi-layered user utility model that leverages on studies of human visual perception and quality of experience (QoE) from the fields of computer graphics and human computer inte...

Peer-to-peer (P2P) TV technology is seen as an emerging alternative to the current systems of providing TV channels and video services over the Internet. However, little information is available on users’ Quality of Experience (QoE) on P2P systems. We discuss the general problems behind subjective assessments of P2P streaming, and present a discussion on the factors affecting QoE for P2P TV. We...

With the recent increased popularity and high usage of HTTP Adaptive Streaming (HAS) techniques, various studies have been carried out in this area which generally focused on the technical enhancement of HAS technology and applications. However, a lack of common HAS standard led to multiple proprietary approaches which have been developed by major Internet companies. In the emerging MPEG-DASH s...

Assessing the Quality of Experience (QoE) for multimedia services transmitted over a network has become a major issue for telecom providers (Telcos), because it can determine the real user satisfaction regarding the service they hire. For this reason, we present the metrics based on the Reduced Reference (RR) methodology called Quality Index Based Frame (IQBF) and New Undecodable Frames Index (...

Recently, network researchers have taken a great interest in quality of experience (QoE) and in the new aspects it brings in the study of the link between network conditions and user satisfaction. Also, the realization that the information of users’ satisfaction can be directly applied in the network management in a real-time manner has resulted in a fair amount of publications. Although the sy...
