Indexing Traditional Uddi for Efficient Discovery of Web Services

Web service is a major trend in the industry for loosely coupled service-oriented architecture and interoperable solutions across heterogeneous platforms and systems. It receives profound attention and adoption by the industry as well as standard bodies. The traditional web service discovery is based on one-way request/response interaction pattern that a client (service consumer) makes a service request to the server (service provider) based on the services specified in the server's WSDL. At the heart of service-oriented computing is a Web service registry that connects and mediates service providers with clients. The Universal Description, Discovery and Integration (UDDI) offers a standard way for businesses to build a registry, discover each other and describe how to interact over the Internet [9].UDDI is however limited in scope that searching if services is possible only by means of keyword which is not enough to justify the capabilities provided by the web services of different service providers. This paper proposes an indexing mechanism to be introduced in the traditional UDDI for effective discovery of web services which focuses on two QoS parameters namely response time and relevancy. Evaluation of the proposed framework is done by implementing the algorithm and performance is compared with the traditional UDDI discovery.
