Transcription

1 Gesellschaft für Informatik e.v. (GI) publishes this series in order to make available to a broad public recent findings in informatics (i.e. computer science and information systems), to document conferences that are organized in cooperation with GI and to publish the annual GI Award dissertation. Broken down into seminars proceedings dissertations thematics current topics are dealt with from the vantage point of research and development, teaching and further training in theory and practice. The Editorial Committee uses an intensive review process in order to ensure high quality contributions. The volumes are published in German or English. Information: ISSN ISBN In 2012, the annual International Conference on Innovative Internet Community Systems (I 2 CS) comes to the knowledge and technology capital of Norway, Trondheim. By its motto Future requires Interdisciplinarity the organizers continue to combine contributions on foundations, technology, applications and socialization of virtual communities. Besides paper presentations, discussions, brainstorming and other, creative activities are enabled. The present LNI volume contains 18 carefully selected contributions of this conference. G.

6 Foreword The Innovative Internet Community Systems (I 2 CS) has grown successfully from a national German workshop, founded in 2001, to a small but valuable international conference. The conference alternates between international and German locations, which are selected by the steering committee. The annual three-day event takes place around the second half of June. Its name is its mission: to make an innovative community comprising of scientists, researchers, service providers and vendors. This year, the community goes north from the German capital towards the polar circle. The close corporation with the Gesellschaft für Informatik e.v. (GI) to publish the presented papers as Lecture Notes in Informatics (LNI) proceedings is continued. A strong peer review by two to three members of the program committee guarantees the high quality of contributions. The present proceedings are structured in six topics, covering the selection of the best submitted papers from Please refer to LNI P-148, P-165 and P-186 for the previous I 2 CS proceedings. To receive a copy of a dedicated volume, please your request to lni@i2cs-conference.org. The width of I 2 CS topics for 2012 spans a unique choice of aspects, bundled into the three classical areas: foundations, technology, applications and socialisation. Ambient Assisted Living (AAL) is given a strong focus in this year. Foundations Theories, models, algorithms for communities Distributed algorithms and simulation models Game theory, graph theory and cost models Innovative communication protocols Self organizationand self stabilization Security and privacy protection Swarm intelligence and collaborative behaviour

8 Preface to the 12 th I 2 CS 2012, Trondheim, Norway It is a great pleasure for us to welcome all participants of the 12th International Conference on Innovative Internet Community Systems I 2 CS 2012 to Trondheim. On behalf of the organizing and program committee, we hope that you will have nice and unforgettable days in the knowledge and technology capital of Norway, Trondheim. "Future Requires Interdisciplinarity" is the motto of the 12 th I 2 CS. The selected venue, the Natural Science Building at the Norwegian University of Science and Technology (NTNU) in Trondheim, is a modern university building, containing all the facilities required for both tuition and conferences. Following the initial concept of keeping the conference small and make it possible for all participants to get to know each other, we selected 18 full papers for presentation. It is the culture of I 2 CS to bring participants together, not only in order to share their latest results and experiences, but also to get to know and to learn about and of each other. We will not contribute to the tendency that conferences just serve the purpose of increasing the authors publication count. We offer an inspiring and unique atmosphere in which everybody will feel comfortable. As the past I 2 CS events have shown, this guarantees an excellent platform to lift the community idea. Hence, participants will not only attend our scientific sessions, but will also spend as much time as possible together to discuss, share opinions or define projects ideas in brainstorming meetings. Last, but not least, a well-chosen cultural program around our sessions will give the participants the possibility to get in contact with both the historical and modern Trondheim. We are pleased to see that, over the years, many colleagues join our conference series over and over again, but in the same manner we appreciate and welcome all people who participate in I 2 CS for the first time and hope they will remain in contact with our community. Next year, the I 2 CS conference will be held in Iserlohn, Germany, and we hope we meet again there. Yours I 2 CS 2012 organizing team Trondheim, June 2012
