Adaptive creation of network applications by a patchwork application module

Abstract

The Ja-Net (Jack-in-the-Net) architecture creates network applications through interactions among application components called cyber entities (CEs). CEs establish relationships with other CEs and cooperatively provide applications with relationship partners. The strength of a relationship is the measure for the usefulness of the partner and adjusted based on the evaluation by users of the application. In Ja-Net, network applications are adaptively created through the formation of a group based on the strength of relationships between CEs (the grouping technique). Through simulations, we evaluate Ja-Net's adaptability and show the limitations of the grouping technique. To enhance its adaptability, we propose a group-patchwork technique, which develops better adapted groups by combining existing simpler groups, and evaluate its effectiveness by simulation. It is confirmed that the group-patchwork technique provides enough adaptability even when it faces a user preference change.
