  Smart environment applications demand novel solutions for managing quality of
services, especially availability and reliability at run-time. The underlying
systems are changing dynamically due to addition and removal of system
components, changing execution environments, and resources depletion.
Therefore, in such dynamic systems, the functionality and the performance of
smart environment applications can be hampered by faults. In this paper, we
follow a proactive approach to anticipate system state at runtime. We present a
proactive dependability framework to prevent faults at runtime based on
predictive analysis to increase availability and reliability of smart
environment applications, and reduce manual user interventions.
