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. In this paper, we present our work in progress on middleware-based system support for proactive adaptation. It offers context information, prediction, and influence via a uniform abstraction, update notifications for subscribed context or predictions, and an application model to determine adaptation alternatives.
