Welcome to a Wireless seminar on Monday May 19 with Professor Markus Fiedler from Blekinge Institute of Tecnology!


Topic: Quality of Experience and Energy Efficiency — Antagonists or Mates?


Speaker: Professor Markus Fiedler, Blekinge Institute of Technology

Day and time: Monday May 19 at 14.30

Location: EIT ICT Labs co-location centre, Isafjordsgatan 26, Kista. Elevator C, floor 3

This talk will provide an overview of our recent work in the intersection of Quality of Experience (QoE) and Energy Efficiency (EE). Upon motivating the need to include EE into QoE considerations, we will review and compare hardware- and software-based power measurements tools. After that, hardware-based power measurements for a set of services will be presented and discussed. We will  then turn to temporal QoE issues in videos, in particular freezing, and reveal quantitative relationships related to EE. The latter will show to which extent QoE and EE come along with each other. Furthermore, ways to reduce energy consumption while keeping the desired level of QoE will be discussed. The talk will also present a set of lessons learned as well as future challenges.


Markus Fiedler has been professor of teletraffic systems at Blekinge Institute of markus-fiedler_webbTechnology (BTH), Karlskrona, Sweden, since 2011. He joined BTH in 1998 after taking the Ph.D. degree in Electrical Engineering with focus on ICT at University of Saarland, Germany. His research interests are focused on enabling and disabling factors for Quality of Experience (QoE) in networks and applications; on the validation of future internet solutions in terms of QoE; on performance measurements, modeling, analysis and control in virtual and wireless environments; and on ecologic and economic sustainability factors in the context of networking, such as energy efficiency. Markus Fiedler has been active in European projects (COST, FP6, FP7) since 1998. In particular, he held several leading positions in a series of Networks of Excellence on future networks (EuroNGI, EuroFGI and Euro-NF), and served as co-chair of the EC’s Future Internet Cluster in 2011 and 2012. He has recently been appointed as Swedish COST Domain Committee member in the area of ICT.
