Ponder2 - A Policy Environment for Autonomous Pervasive Systems

Abstract

Policies form an important part of management activities and are an effective means of implementing self-adaptation in pervasive systems. Many policy- based systems designed to date focus on large-scale networks and distributed systems. Consequently, they are often fragmented, dependent on infrastructure and lacking flexibility and extensibility. This demonstration presents Ponder2, a self-contained, stand-alone policy environment that is suitable for a wide range of applications in environments ranging from single devices, to personal area networks, ad-hoc networks and distributed systems. Ponder2 environments can be federated giving a consistent view of the name spaces within the environments and the ability to propagate events in a transparent manner.
