Component-based software development paradigm enables the construction of complex applications by assembling existing self-contained components. The cost of the software development process can then be sharply reduced. Current software systems are becoming more distributed and operate in highly dynamic environments. Therefore, dependability of component-based applications is an important research issue. Our contribution consists of a diagnosis service that enhances dependability of componentbased applications. This diagnosis service provides the ability of detection and location of faulty components during runtime. In this paper, we describe the application of the proposed diagnosis service to an industrial case study that consists of a heterogeneous sensor data management system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
