AN APPROACH FOR GRAPH BASED PLANNING AND QUALITY DRIVEN COMPOSITION OF WEB SERVICES
S. Justin Samuel, T. Sasipraba · 2011
Service Oriented Architectures enable a multitude of Web services to provide loosely coupled and interoperable services at different Quality of Service level in the recent few years. Dynamic Web services composition offers the opportunity for creating new web services at runtime from those already published in UDDI registry. However, this composition requires necessarily quantifying criteria for Web service selection to build a more appropriate one. As the result, the problem of synthesizing web services of high quality is a prominent issue. To resolve the problem of finding the best composition, quality based graph planning method is used. First we construct the composition planning graph and secondly by applying non-functional quality parameters the best composition schema is found by using iterative method. It provides a unique search space and also it guarantees to find a best solution to a solvable problem.
