Abstract Pervasive systems require minimal user intervention while constantly adapting their configuration and behaviour. For example, a personal area network of sensors and computational devices monitoring the health of a patient needs to be able to reconfigure itself in response to sensor changes (failures/removals or additions), changes in the activities or context of the patient as well as changes in the health of the patient. This tutorial will present the Self-Managed Cell architecture developed at Imperial College in collaboration with the University of Glasgow with par-ticular emphasis on the use of policy-based techniques for implementing adaptation and reconfiguration in autonomous pervasive systems. Policies are rules governing choices in the behaviour of systems and are often en-countered as either event-condition-action rules or authorisation rules, al-though other types of policies such as negotiation, filtering and delegation can be defined. Policies can be used to define management and adaptation behaviours within autonomous cells of devices. In addition, they can govern interactions between and federation of the autonomous cells. During this tutorial we will present aspects of the Ponder2 policy specification and implementation, structuring concepts for interactions between cells and integration of policy driven interpreters event and domain ser-vices. This tutorial will include a hands-on practical session based on the Ponder2 implementation realised at Imperial College. Ponder2 was recently designed as part of the TrustCoM project and has been used in several projects funded by the European Union and the EPSRC. More information about Ponder2 can be found at http://ponder2.net This tutorial is aimed at those interested policy-based architectures for autonomous pervasive systems and will allow attendees to gain direct experience with the Ponder2 system. This tutorial is based on a tutorial previously given at the UKUBINET Workshop 2006. Attendees must have a laptop with Java JDK 5.0 installed (Windows, MAC or Linux platform). Biography Dr Kevin Twidle has conducted research in the Distributed Systems area for many years as part of the Distributed Software Engineering group at Imperial College and where he has given courses in Distributed Systems, Operating Systems and Networking. He pioneered sending data from remote parts of the globe back to the Internet in the 90's. He also spent several years running the real-time, data collection department for a web based sports coverage company in San Francisco. Dr Emil C Lupu is currently a Senior Lecturer in the Department of Computing at Imperial College London where he leads several research projects in the areas of policy-based network and systems management, pervasive computing and trust and security funded by the UK EPSRC, European Union and Industry. Dr Lupu has over 60 publications in these areas and serves on on the program committee of numerous international conferences including the IFIP/IEEE Symposia on Network Operations and Management, the IEEE Int. Conf. on Self-Adaptive and Self-Organising Systems and the IEEE Workshop on Policies for Distributed Systems and Networks. He was a co-founder of the IEEE Workshop on Policies for Distributed Systems and Networks and served as a steering committee member (1999-2006) and as program co-chair (2001, 2004) for this workshop.
