Preface

During spring 2006 the seminar on Internetworking focus on mobile communities. In the early years of internetworking, file transfer, e-mail and WWW were the most popular applications on the Internet. Later on, we have witnessed the power of communities on the Internet, like for example the popular instant messaging and presence systems from late 90's (ICQ, AOL, Yahoo, MS Messenger, etc). During the same time, other powerful communities were built around e-commerce, like eBay and Amazon, and anti-ecommerce content delivery through P2P networks like Napster, Gnutella, Kazaa, and Akamai. Recently we have seen the growth of communities around blogs and VoIP (Skype). It seems evident that community networking is a viable, growing trend in the Internet that people are interested about.

The power of community networking will eventually emerge into mobile environments. Mobile Community can be defined as follows: "A network of interpersonal ties that provides sociability, support, information, a sense of belonging, social identity, and which always connects its members regardless of where they go. It's important to note that location, time and resources are not necessary constraints on membership or participation in a mobile community. However, the community may choose to form based on intended restriction of those variables." [http://www.mobilecommunitydesign.com/]

This seminar focuses on various aspects of mobile communities. Internetworking between mobile and fixed systems is naturally included in many of the topic areas. The seminar articles cover the following topics: group communication, communities in mobile environment, usability, voice over IP services, Skype, presence services, peer-to-peer systems, mobile cellular systems and services, service discovery, security and trust, content distribution, file sharing and business models. The articles cover the mobile communities topic rather broadly: some papers are providing overviews and surveys, while other papers research the topics making also scientific contributions.
