Abstract

As Service Oriented Architecture is expected to grow in the future e-business, web services are believed to be the ideal platform to integrate various business artifacts disparate platforms and systems. QoS(Quality of Service) of web services in terms of performance, reliability, and availability becomes the key issue when web services model complex and mission-critical applications. In this paper, we propose a simulation-based framework that enables web services to be composed based on their QoS properties. The proposed framework iteratively analyzes the QoS of the composite web services with multiple perspectives until the QoS requirements are met to various service users and providers.
