Previous events were held in Vilanova i la Geltru´ (Spain) in 2011, Lulea (Sweden) in 2010, Twente (The Netherlands) in 2009, Tampere (Finland) in 2008,Coimbra (Portugal)in 2007,Bern(Switzerland) in 2006,Xanthi (Greece) in 2005,Frankfurt-Oder (Germany)in 2004and Las Vegas (USA) in 2002.This year’seventwasorganizedandpartiallysupportedbytheSpaceInternetworking Center (SPICE), Democritus University of Thrace in Greece. The conference attracted 50 submissions from 22 different countries in Asia, Europe, North America and Africa. All submissions were subject to thorough review work by the Technical Program Committee members and additional re- viewers. The committee, based on the final paper ranking, accepted 23 papers that were ranked first as regular papers to be presented in different thematic sessions and the next six papers (above threshold) as short papers to be pre- sented in a work-in-progress session. All papers satisfied the criteria of novelty, presentation,relevance,andin addition,demonstratedclearpotential forsignif- icant impact; therefore, all 29 papers were included in the proceedings, as part of the Lecture Notes in Computer Science series. The papers were organized into six thematically distinct technical sessions, covering the following major topics: Virtual Networks and Clouds, Multimedia Systems, Wireless Sensor Networks and Localization, Delay-Tolerant and Op- portunistic Networks, Handover Techniques and Channel Access and Ad hoc Networks. The work-in-progress papers were presented in a dedicated session. Furthermore,anadditionalsessionwithinvitedpapersintheareaofDelay-and Disruption-Tolerant Networks was organized. In WWIC 2012, we particularly emphasized on areas such as Delay- and Disruption-TolerantNetworks(DTNs) andOpportunistic Networkswith a ded- icated technical session, an invited session, one keynote speaker and a very in- terestingpaneldiscussion.AlleventsintheareaofDTNswerekindlysupported and organized by the Space Internetworking Center (SPICE) project. WWIC 2012was pleasedto host the joint ERCIM eMobility and MobiSense workshops,which took place on June 9, 2012. We would like to thank the authors for choosing to submit their results to WWIC 2012, all the members of the Technical Program Committee, the members of the Organizing Committee, as well as all the additional reviewers for their effort to provide detailed and constructive reviews. We are grateful to the two keynote speakers, Eytan Modiano and Jeorg Ott, for accepting our invitation; and to Springer LNCS for their long-term support. Last but not least,we wouldlike to thank the companies ErasmusSA(www.erasmus.gr)and VI Preface LiveEvents (www.liveevents.tv) for providing organizational support and live Internet broadcasting services, respectively. We hope that all participants enjoyed the technical and social conference program, the hospitality of our Greek hosts and the beauty of the conference location. Next year’s conference will take place in St. Petersburg, Russia. We hope to see you there again.
