Policies for Sensor Networks and Home Care Networks

Abstract

This paper describes how a policy-based management system for call control has been generalised and extended, making it applicable to sensor networks and home care networks. The background to these domains is introduced. The previous ACCENT policy system is described, along with the restrictions that previously limited its suitability for other domains. The generalisations needed to the policy system are described. This now relies on layered ontologies that describe common and domain-specific features of the policy system. Conflicts among policies are now handled more uniformly, including tool support for semi-automated detection of policy conflicts. The structure of policies for sensor and home care networks is outlined, together with sample goals and policies that illustrate the new policy languages.
