A Dependability Management Mechanism for Ubiquitous Computing Systems [chapter]

Changyeol Choi, Sungsoo Kim
2005 Lecture Notes in Computer Science  
We validate the autonomic fault management scheme based on a workload model derived from the system log analysis.  ...  Dependability for a ubiquitous computing system must be guaranteed for each single component of a system and for the whole system, whichdesigned to fulfill a certain task-might be more than just a sum  ...  Also, we validate the autonomic fault management scheme based on a workload model derived from the system log analysis with a scenario applicable to the run-time configuration phase.  ...
