On the control of adaptation in ubiquitous computing

A core subclass of Ubiquitous Computing (Ubicomp) applications comprises those that are context-aware, which adapt their behavior to the prevailing resource availability levels aiming to optimize and enrich user-environment interactions and to reduce the demand for user intervention. The problem of adaptation control is related to the orchestration of adaptations carried out by concurrent applications. In this process, the adaptation controller needs to promote system stability and should consider other desirable properties: resource consumption, reactiveness etc. In this paper we introduce ACTUS, an on-going proposal of generic framework for building adaptation controllers targeting Ubicomp.
