Solution to dynamic web service composition related to QoS

Web services technologies are becoming a de facto standard to integrate distributed applications and systems using XML-based standards. Developing applications that support web services interfaces will not be enough to provide complete and coordinated business processes. Thus, we need a new approach to compose these web services together in order to form web services orchestration and processes definition There are two methods for web service composition. One is static composition and the other is dynamic composition. Automated web service composition is a very challenging task. This paper proposes a new dynamic web services composition algorithm to solve the composition issues related to data distribution, reliability, availability and QoS.
