چکیده
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. RÉSUMÉ. Cet article décrit la généralisation et l’extension d’un système de gestion d’appels par politiques. Nous présentons l’adaptation de ce système à deux domaines : les réseaux de capteurs et les réseaux de télésoins à domicile. Nous présentons les concepts fondamentaux de ces deux domaines, le système de gestion de politiques ACCENT, ainsi que les restrictions qui avaient précédemment limité son utilisation à d’autres domaines. Nous décrivons les généralisations dont le système de politiques avait besoin. Le système utilise dorénavant des ontologies en couches pour la description des fonctionnalités communes et orientées-domaine. Les conflits entre politiques sont maintenant traités de manière plus uniforme avec un outil de détection semi-automatique. La structure des politiques pour ces nouveaux types de réseaux est présentée. Des exemples de buts et de politiques sont aussi fournis.

Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...
