Failure Prediction Based Self-healing Approach for Web Service Composition.
Web services can be composed together in order to carry out complex transactions or workflows. During the execution of the composite service, if one component service fails, a mechanism is needed to ensure that the failed service can be quickly and efficiently replaced. In this paper, we propose a selfhealing approach for web service composition. The key issue of such approach is the failure prediction. Based on prediction of the failure, service which will be failed can be detected as soon as possible. Thus, reselection process will be started earlier before the invocation of this service. This will make the reselection process minimize the interrupting time (caused by online re-selection) of the composite service execution and improve the availability of the composite service. The experimentations show better performance of the proposed self-healing approach.
