Dynamic Approach for Web Services Selection

Abstract

Web Service is a software component invoked over the Web via an XML[1] message that follows the Simple Object Access Protocol (SOAP[2]), which is a simple XML based protocol to let applications exchange information over HTTP and to transport the messages using open protocols standard. Web Services are based on distributed technology and provide standard means of interoperating between different software applications across and within organizational boundaries with the use of XML. The purpose of web service selection is to select optimal web service for a particular task. When dynamic discovery is used in Web Services, it is common that the result of the discovery contains more than one provider. The purpose of this work is to develop an approach for secured, dynamic and transparent service selection and to evaluate the proposed architecture in terms of what selection techniques should be applied.
