A Distributed Agent Coalition Algorithm for Web Service Composition

The topic of agent-based service composition has been experiencing much attention. In this paper, a service agent model is proposed, which integrates the Web service and software agent technologies into a cohesive entity. Based on the service agent model, a distributed agent coalition algorithm for autonomic Web service composition named as DACA is proposed. DACA is fully distributed, which is based on the distributed decision making of the autonomous service agents and addresses the distributed nature of Web service composition. The simulation experimental results demonstrate that the proposed DACA is effective for its ability to produce high quality solution at a low cost of communications.
