As the wireless medium is becoming more and more congested, a better use of the scarce frequency spectrum is needed to deliver the required Quality of Service (QoS) to clients. Especially in unlicensed bands, wireless systems suffer from intra-network interference [1], e.g., in professional wireless conferencing environments [2]. Therefore, cognitive solutions are being developed, both on radio and...
This paper discusses results from an exploratory study in which Quality of Experience aspects related to mobile video watching were investigated in a semi-living lab setting. More specifically, we zoom in on usage patterns in a natural research context and on the subjective evaluation of high and low-resolution movie trailers that are transferred to a mobile device using two transmission protocols...
Although Quality of Experience (QoE) plays a major role in the design and development of mobile applications and services, QoE assessment is still challenging, especially in real-life (so called ‘living lab’) contexts. This paper presents results from an exploratory, interdisciplinary study on QoE and more specifically, on the acceptability of varying audiovisual qualities during video watching on...
