Over the past 10 years, it has been witnessed that tremendous growth of Web services as a major technology for sharing data, computing resources, and programs on the Web. With the drastic evolution, adoption and presence of Web services, design of novel approaches for effective Web service recommendation to satisfy users’ potential requirements has become of paramount importance. Existing Web s...

Enhancements in technology always follow Consumer requirements. Consumer requires best of service with least possible mismatch and on time. Numerous applications available today are based on Web Services and Cloud Computing. Recently, there exist many Web Services with similar functional characteristics. Choosing “a-right” Service from group of similar Web Service is a complicated task for Serv...

Web services are software components that can be accessed over the Internet by other software components. Web service workflows are a set of web services that are executed in a structured way. This paper introduces a workflow composer agent, which is able to compose web service workflows, and more importantly, uses semantic descriptions of web services in finding and matching web services for a...

Web service composition has been one of the most researched topics of the past decade. Novel methods of web service composition are being proposed in the literature include Semantics-based composition, WSDLbased composition. Although these methods provide promising results for composition, search and discovery of web service based on QoS parameter of network and semantics or ontology associated...

Service-oriented architectures enable heterogeneous applications to be connected together in order to automate a business process. The shift towards this paradigm is largely due to the development of Web Service technologies. For interoperation, trust formation between Web Services is an important requirement. Currently, Web Services do not support differentiated forms of trust, which is requir...

Web service became one of the important methods for communication through the internet and its usage increased in the levels of users and developers. Semantic web service represents the second generation of web services that contains more description and information about its contents. Searching and dealing with web service is done through process called web service discovery which returns a Se...

Dynamic Web service composition is a process of building a new value added service using available services to satisfy the requester’s complex functional need. In this paper we propose the broker based architecture for dynamic Web service composition. The broker plays a major role in effective and efficient discovery of Web services for the individual tasks of the complex need. The broker maint...

Web-based simulation requires the convergence of simulation methodology and WWW technology (mainly Web Service technology). The fundamental concept of web services is to integrate software application as services. Web services allow the applications to communicate with other applications using open standards. We are offering DEVS-based simulators as a web service, and they must have these stand...
