QoS for Composite Web Services and Optimizing
Yan Gao · Chinese Journal of Computers · 2006
The provision of guaranteed QoS is critical to the success of Web Services in business domains. Thus, how to make the Composite Web Services meet users' QoS requirement becomes a hot issue in the research field. For such reason, this paper proposes a hierarchical structure for Composite Web Service selection oriented QoS including QoS for assuring quality of basic Web services, QoS for evaluating relation degree between services and QoS for measuring the whole quality of Composite Web Services. Based on this, a selection algorithm for QoS-driven Composite Web Services selection is also proposed. The experiment result demonstrates its efficiency.
