Abstract

Service composition is the current research focus in the field of Service-Oriented Computing. However, the service discovery and selection mechanisms are static and not flexible in existing approaches on service composition, and the end-to-end QoS of a composite service can not also be ensured. In this paper, Multi-agent based QoS-aware Service Composition solution (MQSC) is presented, in which the concept of user satisfaction degree is introduced to depict the QoS of the service and the composite service execution mechanism based on Directed Acyclic Graph (DAG) is presented in detail. Through the collaboration between agents, MQSC not only can provide a mechanism for the dynamic service composition but also can ensure the end-to-end QoS of the composite service.
