Theoretical evaluation of ring-based architectural model for middle agents in agent-based system

© Springer-Verlag Berlin Heidelberg 2003. Ring-based architectural model is usually employed to promote the scalability and robustness of agent-based systems. However there are no criteria for evaluating the performance of ring-based architectural model. In this paper, we introduce an evaluation approach to comparing the performance of ring-based architectural model with other ones. In order to evaluate ring-based architectural model, we proposed an application-based information-gathering system with middle agents, which are organized with ring-based architectural model and solve the matching problem between service provider agents and requester agents. We evaluate the ring-based architectural model with performance predictability, adaptability, and availability. We demonstrate the potentials of ring-based architectural model by the results of evaluation
