Toward deeply adaptive societies of digital systems

Modern societies are pervaded by computerized, heterogeneous devices designed for specific purposes, but also more and more often capable of interacting with other devices for entirely different purposes. For example, a cell phone could be used to purchase a train ticket on-line that could later be printed by a vending machine at the train station. This type of open environment is what we call a society of digital systems. In this paper, we outline the characteristics of societies of digital systems, and argue that they call for a new approach to cope with unforeseen interactions, possible incompatibilities, failures, and emergent behaviors. We argue that designers can not assume a closed or homogeneous world, and must instead naturally accommodate dynamic adaptations. Furthermore, self-adaptability, that is, the ability to adapt autonomically to a changing environment, also poses problems, as different adaptation strategies may interfere negatively, leading to unstable behaviors.
