AMUN - autonomic middleware for ubiquitous environments applied to the smart doorplate project

Ubiquitous environments like future office buildings that partly or fully implement a flexible office organization require a sophisticated software system that is highly dynamic, scalable, context-aware, self-configuring, self-optimizing, and self-healing. We propose an autonomic middleware approach for such ubiquitous indoor environments and demonstrate the software by our Smart Doorplate Project. The middleware uses an intensive monitoring on different levels to collect the information needed for the metrics to calculate the 'quality of service provision' used to trigger the self-mechanisms. The global optimization of the system behavior is realized with local monitoring and the exchange of messages between the AMUN (Autonomic Middleware for Ubiquitous environments) nodes. The information exchange between services is based on typed messages to get a more flexible communication paradigm than those of method invocation. (c) 2005 Elsevier Ltd. All rights reserved.
