Abstract

In this paper,we describe the Jack-in-the-Net (Ja-Net) architecture for adaptive services in a large scale,open network environment.Using biologically inspired concepts, Ja-Net achieves built-in capabilities to create/emerge services adaptively according to dynamically changing network conditions and user preferences.In Ja-Net,a service is implemented by a collection of autonomous system components called cyber-entities. Cyber-entities are autonomous with simple behaviors and interact with each other using Ja-Net ACL (Agent Communication Language)to jointly provide a service. For instance,cyber-entities migrates from node to node and and a new cyber-entity to interact with. Also,cyber-entities may establish relationship with interaction partners to form a group to provide a service. Strength of relationship between cyber-entities is a measure for the usefulness of the relationship and is adjusted based on the level of satisfaction indicated by a user who received the service. As relationships grow, cyber-entities self-organize by narrowing the cyber-entities to interact with based on the strength of relationship. Consequently, a group of cyberentities emerge to provide services that users prefer. We implemented a prototype of Ja-Net to verify the feasibility of autonomous interaction and service emergence features of Ja-Net.
