On my way back to academia and it feels just right. After running six editions of the IEEE Workshop on Broafband Wireless Access I am looking forward to learning how this experience will help in my role a Workshop Chair of IEEE ICC 2013.
The 10th International Conference on Wired/Wireless Internet Communications – WWIC 2012 will be held in the magnificent island of Santorini, Greece, on June 4-6, 2012.
The goal of the conference is to present high-quality results in the field of global internetworking, and to provide a framework for research collaboration through focused discussions that will designate future research efforts and directions. In this context, the program committee will accept only a limited number of papers that meet the criteria of originality, presentation quality and topic relevance. WWIC is a single-track conference which has reached, within 9 years, the highest level of quality, which is reflected both in the level of participation as well as the acceptance ratio and the amount and quality of submitted papers. Following the conference tradition there will also be a best paper award.
Accepted papers from the Call-for-Papers (CFP) will appear in the conference proceedings published by Springer in the Lecture Notes of Computer Science (LNCS) Series. Extended versions of selected papers will be considered for publication in a special issue of a competitive international journal.
Along with the Polish EU Presidency this autum“s Future Internet Assembly (FIA) will be part of the Poznan Future Internet Week.
Pretty packed agenda (week) featuring several parallel workshops and sessions. More than 800 delegates registered; thus as usual an excellent opportunity to learn about the EU-research heartbeat from the very center.
Naturally, the FI-PPP is represented at large across several sessions. The highlight will be the FI-PPP Architecture Board meeting on Tuesday.
Will be my last FIA attendance as SAP delegate but surely not my last attendance at all.
Many interesting talks spread over a set of workshops:

Notes of the 5th KuVS GI/ITG Workshop „NG Service Delivery Platforms“ with the topic „Advanced Service Delivery Platforms for Mobile Networks“
QoE optimization with network layer awareness on hybrid wireless networks (T. Melia, S. Randriamasy, Alcatel-Lucent, France; D. Munaretto, M. Zorzi, Univ. Padova/CFR, Italy)
– FP7 Medieval Project
– QoE based resource management in current BWA networks (LTE but also WiFi)
– Qoe Metrics for Video – Compare with reference and/or no reference
– Use the fact that different paths trough the networks means different QoE. Access/path selection based on QoE targets
– IETF ALTO (Application Layer Optimization) Working Group
— Describes attributes of caches and of their locations
— ALTO server provides ALTO clients with info on topology, routing cost, etc
– ALTO stores the network cost and needs to be combined with application layer metrics
– ALTO a tool for the operator to evaluate the performance of network caches
– In Medival ALTO not opened to users, ie operator does not reveal network-internals
Analysis of managed and OTT streaming services in mobile networks (J. Eisl, G. Kuhn, M. Lott, Nokia Siemens Networks, Germany; M. Varela, J. Prokkola, T. Mäki, J–P. Laulajainen, VTT, Finland)
Presented by M. Lott, Head of Service Control & Identity Management
– Compares „managed services“ (with QoS/QoE support by operators) and OTT services
– Different devices, different services (Mobile TV, Streaming Video, etc)
– Measurements via tcpdump, Wireshark, and tool developed by VTT
– OTT services mostly provided over HTTP, some use RTP/RTSP
– Microsoft Smoth Streaming and Apple HTTP Live Streaming are HTTP-based adaptive streaming protocols
– Conclusions: Rate adaptation not widely used, not supported by many servers, HTTP-based adaptations proprietary
– Conclusion: Managed services not significantly better than OTT services
— Paper author/NSN concludes: Means current QoS/QoE mechanisms are ineffective; more research required
FoG and Clouds: On Optimizing QoE for YouTube (T. Hoßfeld, F. Liers, T. Volkert, R. Schatz, Univ. Würzburg, Germany; Univ. Ilmenau, Germany; FTW Vienna, Austria
– Trend away from QoS towards QoE
– How to manage/optimize networks for QoE
– For HTTP-based video streaming there is no „low quality“, video will simply stall if too few resources
– Proposed: YouTube QoE metric that covers „stalling“
– Extensive study with human subjects to identify key criteria for „video quality“
– Mapping between „MOS and Number of Stalls“
– Conclusion: Users accept only very very few stalls (1 to no) and only very short stalls (exponential decrease of MOS)
– Equation for initial caching delay versus bandwidth provisioning
Application and Quality of Experience Aware Resource Management (D. Stähle, Univ. Würzburg, Germany)
– Look for ways to achieve win/win situation through network/user cooperation
– Possible with QoE as metric?
– And for Mesh-Networks?
– AquareYoumon tool by Uni Wuerzburg (Youtube QoE over mesh networks)
– YoMo – client-based application monitoring
MediaCloud – A Distributed Service Platform for Media Services (M. Bauer, S. Braun, P. Domschitz, Bell Labs, Alcatel-Lucent, Germany)
– Pardigm shift expected away from „Big Iron“ approach (datacenter centric) towards distributed „MediaCloud“
– A new approach to „building distributed services“
— Flow-driven model, Atomic execution model;
— Work on media chunks, not IP packets
– G-Streamer framework goes a bit into this direction
Seamless Service Provision in P2P Service Overlays (K. Panitzek, I. Schweizer, M. Ikramy and Max Mühlhäuser, TU Darmstadt, Germany)
– P2P service overlays – distribution and execution of applications, composition of services
– Seamless service migration between peers
– MudoCore middleware – for code migration between peers
– Chord DHT – for distributed service registry
Joined the TPC of the 1st IEEE Workshop on Standards co-located with IEEE ICC 2012.
Taken from the CFP (download):
The workshop objective is to bring together researchers, scientists, and standards experts from both academia and industry to present and discuss advances on telecommunications as well as challenges faced by each. The workshop aims to address recent findings and to present their methodologies, models, technologies, systems, tools, applications, work in progress and experiences.
The workshop technical program will deliver high quality technical as well as visionary papers that will be reviewed and selected by an international program committee representing both academia and industry with a strong standardization background. Topics of interest include, but are not limited to, enhancements to existing systems and communication protocols developed by standards bodies such as the ITU-T, IEEE, IETF, 3GPP, TISPAN, ETSI, OMA, Broadband Forum, or others. Visionary papers on hot topics, work in progress being currently discussed within the above-mentioned standardization bodies are also welcome.
