A talk "Trade-Offs for Video-Providers in LTE Networks: Smartphone Energy Consumption Vs Wasted Traffic“ was given by Christian Schwartz (University of Würzburg) at the 22nd ITC Specialist Seminar on "Energy Efficient and Green Networking (ITC SSEEGN 2013)", co-chaired by Phuoc Tran-Gia and Krys Pawlikowski, co-located with the Australasian Telecommunication Networks & Application Conference (ATNAC) 2013.  This year's edition of the conference focuses on the impact of green networking on ICT performance, Quality of Service and Quality of Experience, as well as operational expenditures which are major goals of SmartenIT. The current trends in green networking and the impact of the required changes to ITC equipment and protocols on other stakeholders were discussed. Further energy-aware performance models and metrics being important for SmartenIT were also in the scope.

The talk by Christian Schwartz showed the trade-off between end user in terms of energy consumption and service provider in terms of cost and delivery bandwidth vor video streaming services which is one of the selected SmartenIT applications. As an outcome, it is shown that traditional traffic management approaches are not able to satisfy the contradicting goals of the stakeholders in the SmartenIT ecosystem. 1) Network configuration in terms of timer selection in LTE/3G networks is not possible. 2) Application traffic configuration is also not possible Therefore, new traffic management approaches are required. Here, SmartenIT can help to overcome this real world problem. Discussions yielded new insights in stakeholder dynamics to consider when optimizing energy consumption while considering QoE and preventing network outages due to signalling overload with Economic Traffic Management.
