The European Conference on Computer and Network Defense draws contributions and participation both from academia and industry, and addresses security from multiple perspectives, including state-of-the-art research in computer network security, intrusion detection, denial-of-service, privacy protection, security policies, and incident response & management. The conference is organized jointly by the Institute of Computer Science of the Foundation for Research and Technology - Hellas (FORTH) and the European Network and Information Security Agency (ENISA).

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.

WWIC2008wasorganizedbytheTechnicalUniversityofTampere, Finland, and it was the sixth event in a series of InternationalConferenceson Wired/Wireless Internet Communications. Previous events were held in Coimbra (Portugal) in 2007, Berne (Switzerland) in 2006, Xanthi (Greece) in 2005, Frankfurt (G- many) in 2004, and Las Vegas (USA) in 2002. The WWIC 2008 call for papers attracted 67 submissions from 33 co- tries, which were subject to thorough review work by the Technical Program Committee members and additional reviewers. The selection process resulted in acceptance of 18 papers, organized into 6 single-track technical sessions. The WWIC 2008 main technical program covered studies on performance analysis of wireless systems, topics on resource and QoS management, and issues on implementation techniques, mobility, cross-layer design and wireless sensor n- works. The technical program was complemented by two keynote speeches, by Nestor Peccia (European Space Agency, Darmstadt, Germany) on "Interpla- tary Internet," and Arto Karila (Helsinki Institute of Information Technology, Finland), on"Multi-Accessin RegionalNetworks."Inadditionto themainte- nicalprogram, thelastdayoftheconferencewasdedicatedtotheSecondERCIM workshop on eMobility. WWIC has been selected as the o?cial annual conference by COST Action 290 (Wi-QoST-Tra?c and QoS Management in Wireless Multimedia Networks) since 2005, and this time the conference was co-located with the ?nal mana- ment committee meeting of the Action. For that reason, two sessions of WWIC were dedicated to the Action, and in those sessions a distinguished selection of the results of COST Action 290 were presented. Those papers were selected from the submissions to the general call for papers according to the same strict criteria as the other accepted papers.
