Mediating Web Services for Dependability (2008)

Author(s): Chen Y, Romanovsky A

    Abstract: The paper presents a novel approach to improving dependability of Web Service composition. The proposed architecture, called WS-Mediator, relies on an off-the-shelf mediator solution implementing run-time dependability monitoring and assessment, resilience-explicit computing and fault tolerance mechanisms used together to achieve dependable dynamic Web Service integration. We have implemented a Java WS-Mediator framework based upon the WS-Mediator concept, which can be easily integrated into Java Web Services applications. The paper reports results of the exten-sive experiments conducted in the context of the bioinformatics and virtual organization domains, which demonstrate the applicability of our approach.
