Abstract :
This project presents modeling, prototyping and results of the middleware developed for Web service dynamic selection in Web services composition named DWSC-M (Dynamic Web Service Composition Middleware). DWSC-M´s main focus is to choose what Web services will be part of the composite Web services in runtime. The choose is made considering aspects of QoS - Quality of Service. To evaluate this approach two algorithms for Web Services selection has been proposed and implemented: the first one uses Random Selection (RS) and the second one uses Euclidean Distance (ED) for the selection of services and considers for this purpose the QoS attributes requested by a client.
