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.

TheInternationalConferenceonWired/WirelessInternetCommunications(WWIC)was held for the second time, following a successful start in 2002, in LasVegas. The goal of theconferencewastopresenthigh-qualityresultsinthe?eld, andtoprovideaframework for research collaboration through focused discussions that designated future research efforts and directions. The number and the quality of submissions indicate that we are well on the way to establishing WWIC as a major event in the ?eld of wired/wireless internet communications. We received around 60 competitive submissions from Europe, North America, the Middle East and the Far East. Each submission was reviewed by at least two experts, although the majority received three or more reviews. Based on this rigorous reviewing procedure, the International Program Committee selected 26 submissions for presen- tion and publication in the proceedings. Therefore, we should all expect the quality of a selective conference in this volume. We hope you will enjoy it. The papers selected for presentation at WWIC 2004 were stimulating and of utmost interest. They were organized into eight sessions: 1. Protocol engineering and energy ef?ciency in wireless networks 2. Mobility management and mobile devices 3. Transport layer and congestion control 4. Architecture, implementation and experimentation 5. Network and protocol modeling 6. Wireless network scheduling and analysis 7. Multimedia distribution and group communication 8. Service discovery. We would like to thank the authors for choosingWWIC 2004 to submit their results. We would also like to thank all the members of the Technical Program Committee, as well as the additional reviewers, for their effort to provide detailed and constructive reviews
