A pervasive system features a plethora of devices, services and applications organized as a large distributed system. One approach to managing such systems is by policies where administrators specify the management action to be taken in different situations using Event-Condition-Action (ECA) rules. An important problem with policy-based management of a(More)
Ubiquitous Computing Environments feature massively distributed systems containing a large number of devices, services and applications that help end-users perform various kinds of tasks. One way by which administrators and end-users can manage these environments is through the use of policies. In particular, obligation policies are used to specify what(More)
Ubiquitous computing envisions a habitat where the abundance of mobile devices, services and applications allows the physical and virtual worlds to become seamlessly merged. Users in such a habitat can access their applications and data anywhere and anytime, and perform everyday tasks with greater ease. Applications are not bound to any single device but(More)
Enterprise and grid computing systems are complex and subject to a broad range of changes such as configuration updates, failures, and performance degradations. These changes affect infrastructure elements such as computation and storage nodes, applications, and system management elements such as monitoring infrastructures. Today's best practices in use by(More)
Pervasive systems are complex distributed systems containing heterogeneous and mobile devices, services and applications. Policy-based management is an effective approach for managing these systems. The dynamism of a pervasive system due to mobility of devices and applications makes policy specification and management a difficult problem. Policies need to(More)
