POSTER Towards Proactive Adaptation in Pervasive Environments

Abstract

Pervasive computing applications can adjust their behavior to a multitude of information deemed to be relevant for their situation, their so-called context. Thus far, however, adaptation in such context-aware systems is reactive and limited to the application itself. These restrictions inevitably delay adjustments to events. They cause frequent reconfigurations, and may result in inferior overall system configurations. To remedy these shortcomings, we propose a framework for proactive adaptation that supports applications in preparing for, or counteracting, upcoming context events. The framework consists of (i) a context management component with prediction capabilities, (ii) an application model for calculating adaptation alternatives, and (iii) a pool of adaptation strategies for decision-making.
