Workshop on Sustainability and QoE Management

Workshop on Sustainability and Quality of Experience Management (Friday, June 23rd)

Sustainability is one of the major challenges humankind is facing, spanning a broad range of different goals, ultimately aiming to preserve the ecosystem we all are living in. A solution space needs to include economic, ecological and societal factors, and these solutions need to be provided from a holistic, cross-disciplinary point of view. Digitalization technologies are seen as a means to address many of the problems related to sustainability like reducing inequalities, providing high quality of teaching for everyone on the planet, or tackling climate change by reducing the carbon footprint compared to non-digitalized societal sectors.

Recent technological advances have enabled a constant proliferation of novel immersive and interactive services that pose ever-increasing demands to the communication ecosystem. The rise of the Metaverse, utilizing immersive environments and extended reality, is only the most recent example aiming to reduce travel needs while preserving similar social experiences compared to meeting in person. Such services mark a shift from today’s throughput-orientation towards delay-sensitive services with stringent low latency requirements.

At the same time there is a rise with respect to the number of end devices, type of services and applications, and the application complexity. AR applications are characterized by multi-modal stimuli, e.g., visual, haptic, scent or temperature, with each of these sensory inputs sent having different QoS requirements and traffic patterns. Moreover, the dominance of mobile devices also introduces concerns about power usage and battery duration, which also aligns with environmental concerns about the impact of these services on CO2 emissions, promoting energy efficiency and sustainability also as issues to consider in these contexts.

Following a recently held Dagstuhl Seminar on Quality of Sustainable Experiences we invite the research community to participate in a 1-day workshop to further foster community building and joint exchange of ideas and current research results. We are aiming to compile an interesting program of invited and proposed lightning talks, combined with much room for discussions and potential break-out sessions. Inspired by the style of Dagstuhl seminars, the workshop will not be centered around presentations, but rather a fluent exchange of ideas around topics of common interest in the field of QoE Management, with sustainability as a common thread. The goal of this gathering is to find topics of common interest, and foster future research cooperation around them.

Submission instructions

Each participant is expected to submit a short abstract (<1 page, to be vetted by the TPC for topic fit with the workshop) via EDAS before May 22, 2023, and to give a short presentation during the workshop. The abstracts will be made available via the QoMEX webpage before the workshop. Abstracts should be formatted using the standard IEEE template found here. The organizers will cluster the statements around common areas/topics, and group discussions will be held to develop common positions. Afterwards, a panel session (with one panelist from each cluster) will be held to summarize the discussions of the day, and propose concrete research actions to be worked on, hopefully fostering collaboration between the participants.
