The Second IFIP Workshop on Autonomic Communication (WAC 2005) took place on October 2–5 2005 in Athens Greece. The previous (and first) edition of WAC took place in Berlin in 2004 and its next (and third) edition in Paris in 2006. The workshop was organized by the National and Kapodistrian University of Athens and was supported by the EU funded IST FET Autonomic Communication Coordination Action (ACCA – IST 6475). Additional support was provided by the EU funded IST Network of Excellence E NEXT (IST 506869). Finally IFIP TC6 provided scientific sponsorship through Working Groups IFIP WG6. 6 (Management of Networks and Distributed Systems) and IFIP WG6. 3 (Performance of Communication Systems). The workshop was organized at a time when the – yet to be well defined – field of autonomic communication (AC) is attracting the interest of both the scientific community and the research funding organizations. The latter is manifested on one hand by the numerous recent relevant research exploratory forums workshop panels preliminary forward looking position papers research outlooks and frameworks and on the other hand by the commitment of the FET program of the European Commission in Europe to funding long term research in this area for the next four years. Consequently the second edition of WAC was highly exploratory and included a nice mix of technical work addressing some already identified problems and well articulated ideas on the direction this field should take and the fundamental problems whose solution would enable autonomicity.
