A QOS AWARE QUANTITATIVE WEB SERVICE SELECTION MODEL

Web service is a core technology for sharing information resources and integrating processes in companies or organizations. As the number of applications connected by Web service is increased, the importance of Web service quality tend to be the critical factor in determining the performance of IT system. Web Service selection is also an indispensable process for web service composition as to select best web service to a client's requirement. In this paper, we have proposed a web service selection model using Analytic Hierarchy Process which is used to select best web service based on QoS Constraints. The QoS manager actuates as an agent for service providers and clients to perform publish and find web service operations. The QoS attributes of a web service such as response time, throughput, reliability, availability and cost will be optimized and ranked by the Analytic Hierarchy Process. The highest ranked service will be selected and provided to the requested for further processing.
