From Resilient Computing Architectural Concepts to Wireless Sensor Network-Based Applications (Short Paper)

Resilient computing is defined as the ability of a system to remain dependable when facing changes. To mitigate faults at runtime, dependable systems employ fault tolerance mechanisms such as replication techniques. These mechanisms have to be systematically and rigorously applied in order to guarantee the conformance between the application runtime behavior and its dependability requirements. To this end, we propose architectural concepts for developing resilient computing systems using component-based middleware. The development process of adaptive fault tolerance (AFT) is shortly presented. We then illustrate the benefits of AFT on a Wireless Sensor Network-based application for parking management.
