Dependability for a ubiquitous computing system must be guaranteed for each single component of a system and for the whole system, which—designed to fulfill a certain task—might be more than just a sum of its components. Ubiquitous computing systems must enable the testing not only each of software components separately but also of the whole system. In this paper, we propose a management mechanism for applying software rejuvenation technology into a ubiquitous computing system. It adopts the automatic monitoring scheme, the automatic analysis scheme, the autonomic plan and the execution scheme to suggest the optimal configuration alternative of a ubiquitous computing system. We validate the autonomic fault management scheme based on a workload model derived from the system log analysis.
