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.

The seventh edition of the International Conference on Wired/Wireless Int- net Communications (WWIC) was organized by the University of Twente in May 2009. Since the ?rst event in 2002, WWIC has been established as a highly selectiveconferencefocussingonthe rapidlydeveloping?eldof wirelessnetwo- ing, and providing an international forum for the presentation and discussion of cutting-edge research in the ?eld. The WWIC 2009 call for papers attracted 39 submissions from 20 countries, which were subject to thorough review by the Technical Program Committee members and additional experts. The selection process resulted in the acc- tance of 13 papers, organized into 4 technical sessions. The major themes of WWIC this year were energy e?ciency, security, reliability, and routing p- tocols in wireless sensor and ad hoc networks as well as handover and mobility managementin heterogeneousenvironments. We aregratefulto MatthiasGro- glauser (Nokia Research Center, Finland, and EPFL Lausanne, Switzerland), who accepted our invitation to give the WWIC 2009 keynote speech. Further, we would like to thank Hans Appel (Sun Microsystems, The Netherlands), and Remco Litjens (TNO ICT, The Netherlands) for giving invited presentations at this year's event. In addition to the main technical program, the third ERCIM workshop on eMobility took place on the ?rst day of WWIC 2009. We thank the authors for choosing WWIC 2009 as the conference to submit their results to.
