摘要

该项目展示了为Web服务组合中的Web服务动态选择而开发的中间件的建模、原型和结果，该中间件名为DWSC-M(动态Web服务组合中间件)。DWSC-M的主要关注点是在运行时选择哪些Web服务将成为组合Web服务的一部分。选择是考虑QoS -服务质量方面。为了评估这种方法，已经提出并实现了两种Web服务选择算法:第一个使用随机选择(RS)，第二个使用欧几里得距离(ED)来选择服务，并为此考虑客户端请求的QoS属性。

Dynamic Web Service Composition Middleware: A New Approach for QoS Guarantees

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 evalute 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 atributes requested by a client.
