Web service is an emerging paradigm in which loosely coupled software components are published, located and invoked on the web as a part of distributed applications. The advantage of employing web service composition is to create and consume a value added service by composing simple and complex software components which are deployed at different locations in an autonomic manner. The centralized web service composition approaches suffer from performance bottleneck and a single point failure. The web services are also distributed across geographical boundaries and they may be constantly removed or upgraded.
