This book constitutes the proceedings of the 4th International Conference on Internet Science held in Thessaloniki, Greece, in November 2017.

The 34 papers presented were carefully reviewed and selected for inclusion in this volume. They were organized in topical sections named: next generation community engagement; online policy, politics and co-creation; understanding and empowering digital citizens; data-driven research and design; social media and online interaction.

This volume of the Lecture Notes in Computer Science series contains the set of papers accepted for the two co-located NGC/ICQT2003 workshops, i.e., the 5th COST 264 International Workshop on Networked Group Communications (NGC) and the 3rd - ternationalWorkshopon InternetChargingandQoSTechnology(ICQT),bothof which took place at the University of the Federal Armed Forces Munich (UniBwM), Germany and were hosted by the Information and Systems Laboratory, IIS. NGC2003wasthe ?fth workshopin a continuingseriesof highlysuccessfultech- cal meetings on group communications within the framework of the COST Action 264 "Networked Group Communications," following previous events in Pisa, Italy, 1999, Stamford, USA, 2000, London, UK, 2001, and Boston, USA, 2002. ICQT2003 was the latest edition of a vivid workshop on Internet economics and charging technology; previous events took place in the framework of the Annual Meeting of the German - ciety for Computer Science (GI) and the Austrian Computer Society in 2001 in Vienna, Austria, and in Zuri .. ch, Switzerland in 2002, co-located with the QofIS2002 workshop.

Welcome to the 3rd International Conference on Wired/Wireless Internet C- munications (WWIC). After a successful start in Las Vegas and a selective c- ference in Germany, this year’s WWIC demonstrated the event’s maturity. The conference was supported by several sponsors, both international and local, and became the o?cial venue for COST Action 290. That said, WWIC has now been established as a top-quality conference to promote research on the convergence of wired and wireless networks. This year we received 117 submissions, which allowed us to organize an - citing program with excellent research results, but required more e?ort from the 54 members of the international Program Committee and the 51 additional reviewers. For each of the 117 submitted papers we asked three independent - viewers to provide their evaluation. Based on an online ballot phase and a TPC meeting organized in Colmar (France), we selected 34 high-quality papers for presentation at the conference. Thus, the acceptance rate for this year was 29%.

Welcome to the proceedings of the 4th International Conference on Wired/ Wireless Internet Communications held at the University of Bern from May 10–12,2006. As in 2005,WWIC was selected as the o?cial conference by COST Action 290, and Springer accepted to publish the conference proceedings in the LNCS series. These facts have helped to again attract a large number of hi- quality paper submissions. We received 142 submissions out of which 29 papers were selected by the International Program Committee for presentation at the conference. This resulted in a low acceptance rate of 21%. To limit the load on individual Program Committee members, we increased the Technical Program Committee sizeto 63 members. An additional60reviewerssupportedthe review process. We would like to thank all TPC members and reviewers for their ca- ful reviews, Microsoft Research for providing the online conference management toolkit, and TNO Delft for hosting the physical TPC meeting. The selected papers are organized into eight sessions on the following topics: – Wireless Networks – UMTS and OFDM – Mobile Ad-Hoc Networks – Power Saving and Sensor Networks – Voice and Video Over Wireless Networks – Mobility – TCP – Signalling, Charging, and Security The selected presentations and invited talks from distinguished international speakers formed an extremely exciting program. We hope that all attendees enjoyed both the scienti?c and social program as well as the city and the s- roundings of Bern, the capital of Switzerland.

This workshop on “Protocols for High-Speed Networks” is the seventh in a s- cessful series of international workshops, well known for their small and focused target audience, that provide a sound basis for intensive discussions of hi- qualityand timelyresearch work. The location of the workshop has alternated between Europe and the United States, at venues not onlyworth visiting for the workshop, but also for the distinct impressions theyleave on the participants. The ?rst workshop was held in 1989 in Zurich. Subsequentlythe workshop was moved to Palo Alto (1990), Stockholm (1993), Vancouver (1994), Sophia-Antipolis/Nice (1996), and Salem (1999). In 2002, the workshop was hosted in Berlin, the capital of Germany. PfHSN is a workshop providing an international forum that focuses on issues related to high-speed networking, such as protocols, implementation techniques, router design, network processors and the like. Although the topics have shifted during the last couple of years, for example, from parallel protocol implemen- tions to network processors, it could be observed that high speed remains a very important issue with respect to future networking. Traditionally, PfHSN is a r- ativelyfocused and small workshop with an audience of about 60 participants.

Die 15. GI/ITG-Fachtagung Kommunikation in Verteilten Systemen (KiVS 2007) befasst sich mit einer großen Vielfalt von innovativen und zukunftsorientierten Fragestellungen. Sie spannt dabei einen Bogen von Overlay- und Peer-to-Peer-Netzen über Sensornetze und mobile Ad-Hoc-Netze bis zu Web Services. Die KiVS 2007 dient der Standortbestimmung aktueller Entwicklungen, der Präsentation laufender Forschungsarbeiten und der Diskussion zukunftsträchtiger Ansätze für die Kommunikation in verteilten Systemen.
