An Agent and multi-criteria methods based approach for Web service selection

Abstract

With the significant growth of the number of ser- vices on the Internet, the selection of a web service among several similar services has become a very delicate task for the web services client. In this paper, we propose an approach based on the MCDM methods for selecting the best services. Our approach is composed of two main steps, i) we use the AHP method to assign weights to each non-functional property that qualify a Web service. ii) We use these weights to rank the list of the similar services in order to select the best one. For ranking services we use the TOPSIS method. We implemented our approach as a distributed solution based on a set of Agents that interact together in order to obtain the best desired service as fast as possible. The use of Agent allows to improve the efficiency of the proposed approach. To demonstrate the applicability of our approach we have used a set of real services related to SMS sending. The obtained results shows the efficiency of our approach.
