Low Cost Mechanism for QoS-Aware Re-Planning of Composite Service
To meet the business and user requirements, it is crucial to manage the Quality of Service (QoS) of composite web service. Due to the dynamics nature of the web services, the runtime behavior of web services is likely to differ from the initial estimated one. Therefore, a re-planning to adapt the composite service to the QoS violated services, ensuring the global constraints and preferences will be needed. In this paper, we propose a low cost mechanism for re-planning. Such mechanism is supported by an offline re-planning execution environment and a performance prediction based low cost policy. The experimentations show better performance of the mechanism.
