In the area of mathematical probl- solving, Po 'lya gave the term "the inventors paradox" to such situations, where generalizing the problem may simplify the solution. The dramatic growthof d- tributed systems, peer-to-peer distribution networks, and large grid computing environments confronts designers with serious di?culties of complexity and has motivated the call for systems that self-recover, self-tune, and self-manage.

The Symposium on Self-Stabilizing Systems (SSS) is the main forum for - search in the area of self-stabilization. Previous Workshops on Self-Stabilizing Systems (WSS) were held in 1989, 1995, 1997, 1999, and 2001.The previous Symposium on Self-Stabilizing Systems (SSS) took place in 2003. Thirty-three papersweresubmitted toSSS2005byauthorsfromEurope(16),NorthAmerica (8), Asia (4), and elsewhere (5). From the submissions, the program committee selected 15 for inclusion in these proceedings. In addition to the presentation of these papers, the symposium event included a poster session with brief pres- tations of recent work on self-stabilization.
