Efficient Discovery and Ranking of Web Services Using Non-functional QoS Requirements for Smart Grid Applications

Web service discovery is the important process and traditional methods use keyword-based search to locate the appropriate web service. This method may not yield good results. Non-functional QoS parameters of a web service play a vital role in ranking a web service. Moreover, standards such as UDDI, WSDL and SOAP have potential of providing QoS based web service discovery. In this paper, a new method is proposed to rank the web services. The proposed method computes relevancy function value of the web services and normalization is performed. This normalized result is used to rerank the web service. The selection of appropriate web service provide user to access smart grid over internet. The experimental results show that the proposed method is effective in selecting appropriate web services than traditional methods
