Performance and scalability issues in mobile agent based workflow systems

There is an ever-increasing demand for better performance and scalability i n workflow systems. We describe how mobile agents can be used to satisfy su ch a requirement. For the purpose two important design issues are pointed o ut in workflow execution and architecture levels. Agent delegation models a nd a 3-layer architecture are suggested in mobile agent based workflow syst ems as a solution for each consideration. Workload is statically distribute d over task performers based on the proposed method. As a result the perfor mance and the scalability are improved. The effectiveness is shown through stochastic Petrinets simulation through comparison with client-server based - and another mobile agent-based workflow systems.
