Quality of Experience: Framework, Evaluation and Challenges

There is no doubt that relationships and interactions between Internet and society are complex and bidirectional, leading to a co-evolution of both systems. The Internet exists because humans need networking and the Internet evolution is ultimately driven by the ever-increasing use of it. Within such a dynamic and evolving paradigm basic challenges/questions that need to be addressed include: Challenge 1: Given “behavior”, what underlying (communication) structure (subject to constraints) gives best performance? Challenge 2: Given structure (and constraints), how well can “behavior” be executed?

However a human’s actual requirements, behavior and expectations for the Future Internet cannot be defined or mapped in a static and/or strict way (values and/or thresholds), but rather depend on context and user factors, such as background noise, socioeconomic status, personal experiences and expectations, as well as the importance of the (multimedia) content to the user. As a consequence, performance and quality evaluation depend on these factors. Services – for communication between humans or between humans and machines – have mainly been evaluated following two independent paradigms: On the one hand, metrics of system/network performance have been developed to quantify the characteristics of the system/network and its underlying components (Quality of Service-QoS); on the other hand, independent subjective evaluation has been carried out to analyze the quality perceived by actual users (Quality of Experience-QoE).

There is no doubt that offering high QoE stimulates technology adoption and enhances end-user satisfaction and loyalty. Recently, there has been a shift towards more user-centric approaches in innovation research to bridge the gap between technical parameters and human experience factors. In view of such efforts, the objective of the Special Session is to address a wide range of issues associated with the need for a dynamic, interdisciplinary, approach that formalizes the correlation and impact of User Experience (UX) and/or QoE to QoS that can be engineered and provided within the network.

The Special Session aims to combine peer-reviewed original technical research papers and invited presentations in this challenging emerging interdisciplinary area. This will allow Special Session participants to obtain a wide perspective of this emerging research trend, along with the technical and business challenges associated with it.

    This event is technically endorsed by the IEEE ComSoc Technical Committee on Communications Systems Integration and Modelling (TC-CSIM), by the IEEE QoE for Multimedia Communications Interest Group (QoEIG), and by the COST Action IC 1003 Qualinet (http://www.qualinet.eu/). Papers accepted for the Special Session will be included in the conference Proceedings, IEEE Xplore and the EI Index, with the exception that IEEE reserves the right to exclude any paper from distribution after the conference (i.e., it will not be included in IEEE Xplore) if the paper is not presented at the conference. Papers that are removed from IEEE Xplore will also not be available through the EI Index.
