Non functional QoS criterion based web service ranking

Abstract

Web Services provides a systematize way to integrate web applications over an internet protocol. As numerous web services exist in the internet, selecting appropriate web service is vital in many web service applications. Quality of Service (QoS) is the predominant parameter which is used for selecting a web service in terms of their quality. Based on user’s preference for service quality, services are ranked and best web services are selected. But the difficulty with this approach is that it is strenuous to precisely define QoS property. Hence an enhanced fuzzy multi attribute decision making algorithm for web service selection is presented in this paper. The proposed method periodically collects user’s feedback to update the web service QoS ranking. Experimental results show that the proposed method can satisfy service requester’s non-functional requirements.
