Algorithm for Web Service Composition using Multi Agents

term Web Services describes a standardized way of integrating Web-based applications using the XML, SOAP, WSDL and UDDI open standards over an Internet protocol backbone. Merely providing services to the users in the heterogeneous distributed environments, service oriented systems are very important. Most of the time, the individual services do not have the sufficient conditions to provide any services to the users. In order to resolve the aforementioned problem, one may compose several individual services together. The proposed method currently applied to ensure the robustness and dependability of Web Services compositions do not effectively map to more open dynamic environments. The proposed approach has a new multi-layer Web Services composition model based on Multi-Agent System. We propose a different self-adaptive mechanisms corresponding to different environment's evolutions to improve the reliability of Web Services composition efficiently. Also we introduce an algorithm for dynamic approach to select the best composition. This composition is selected based on the quality and the compose-ability of participated services. Advantage of the proposed approach is to recognize the feasibility of the composition process at any point of execution and produce better throughput and a less consumption of memory to select composition of services dynamically.
