Abstract

To deal with the problems such as Web Services selection algorithm, availability of Web Services composition and QoS (Quality of Service) guarantee, presents a model for Web Services composition based on QoS and providers´ benefit. In this model, the traditional UDDI is expanded to describe the QoS attributes of Web Services. A Service Proxy role is added into this model. All Web Services compositions requested by service consumers are fond, bound and invoked by the Service Proxy role. In order to maximize services providers´ benefit, presents a Service Request Queue Scheduling algorithm in the Service Proxy role. This model meets the QOS requirements of service consumers, guarantees the availability of Web Services composition and maximizes service providers´ benefit. Experimental results confirm the efforts of this model.
