Mobile-Agent-Based Web Service Composition

摘要

In this paper we propose a mobile-agent-based web service composition (MAWSC) model for the dynamic web service composition (WSC). As compared with the traditional WSC models, our model avoids bottleneck of data transfer by peer-to-peer approach. As it achieves the composition without a centralized control, there is no center needed and every WSC portal can offer services for a large quantity of clients. In MAWSC model, WSC client inputs the specification and the initial parameters through WSC portal; then, system creates mobile agents to achieve the task and return the final results back to the client. In this paper, we define "planning" to specify the logic actions of mobile agent so as to execute the WSC automatically. And we also give the process mapping rules to convert the specification of WSC to the planning, and the behavior matching algorithms to map the planning to the physical behaviors of agents.
