An Adaptive Agent Coordination Framework for Web Services Composition

Web service composition is an important technology for agile inter-enterprise application integration. Centric composition engines are widely adopted to enact composite services in many Web service composition research projects. Such a centralized architecture, however, results in problem of scalability, message exchange efficiency, autonomy and adaptation. To deal with the problems discussed above, an adaptive agent coordination framework for service composition is proposed in this paper. Firstly, an agent-based framework for Web services composition is presented. Next, agent model and agent conversation are proposed. Finally, an algorithm of process partition is introduced and the adaptation of service composition is discussed. Simulation results indicate that this framework can support highly concurrent requests and large volume of data more effectively than traditional architecture, so it is helpful to improve the scalability of composite services.
