Abstract

This paper proposes an approach to adapting services in a distributed system whose computational resources are dynamically changed. It supports the notions of cellular differentiation and dedifferentiation. When a service delegates a function to another component coordinating with it, if the former has the function, this function becomes less-developed and the latter's function becomes well-developed. When some differentiated services are not available, it enables remaining services to automatically support the functions provided from the unavailable services. The approach was constructed as a middleware system and allowed us to define agents as Java objects. We present several evaluations of the framework in a distributed system.
