The current book provides a final report of activity performed by the COST 290 Action, ‘‘Traffic and QoS Management in Wireless Multimedia Networks,’’ which ran from March 10, 2004, until June 3, 2008. After an introduction to the COST framework and the Action’s survey time-frame and activities, the main part of the book addresses a number of technical issues, which are structured into several chapters. All those issues have been carefully investigated by the COST 290 community during the course of the project – the information presented in this book can be regarded as ultimate for each particular topic; every open research issue addressed in the book is described carefully, corresponding existing studies are analyzed and results achieved by the COST 290 community are presented and compared, and further research directions are defined and analyzed. Because the book covers a wide area of research addressing issues of modern wired and wireless networking at different layers, starting from the physical layer up to the application layer, it can be recommended to be used by researchers and students to obtain a comprehensive analysis on particular research topics including related areas, to obtain broad and ultimate referencing, and to be advised on current open issues. COST 290 is one of the Actions of the European COST Program. Founded in 1971, COST is an intergovernmental framework for European Cooperation in the field of Scientific and Technical Research, allowing the coordination of nationally funded research on a European level.

This book constitutes the refereed proceedings of the Third International Conference on Wired/Wireless Internet Communications, WWIC 2005, held in Xanthi, Greece in May 2005.The 34 revised full papers presented were carefully reviewed and selected from 117 submissions. The papers are organized in topical sessions on mobility management, transport protocols and congestion control, QoC and routing, quality of service, wireless multi-hop networks and cellular networks, ad-hoc networks, IEEE 802.11 and other MAC protocols, and energy efficiency and resource optimization.

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.

The Internet has evolved from an academic network for data applications such as le transfer and net news, to a global general-purpose network used for a variety of different applications-electronic mail, voice over IP, television, peer-to-peer le sharing, video streaming and many more. The heterogeneity of applications results in rather different application requirements in terms of bandwidth, delay, loss, etc. Ideally, the underlying network supports Quality-of-Service parameters such that - plications can request the desired services from the network and do not need to take actions by themselves to achieve the desired communication quality. Initially, the Internet was not designed to support Quality of Service, and only in the last decade have appropriate mechanisms been developed. Those mechanisms operate mainly on theInternetProtocol(IP) level,butalso network-speci cmechanisms-e. g. ,targeted to particular wired/wireless access network technologies-are required.The goal of the European 6th Framework Programme (FP6) Integrated Project "End-to-end Quality of Service Support over Heterogeneous Networks" (EuQoS) was to develop, implement and evaluate concepts and mechanisms to support QoS end-to-end, meaning that QoS mechanisms in end systems, access networks, inter- main links and within domains must be supported. The EuQoS project developed an impressiveset ofinnovativesolutionsandnovelscienti cideastosupportend-to-end QoS on the Internet. New mechanisms and concepts were designed and implemented in a European-wide distributed testbed. In addition to the rather technical design and implementation work, the project also developed training material introducing basic QoS mechanisms and techniques.
