Pervasive systems refers to
context-aware systems that can sense their context, and adapt their
behaviour accordingly to provide adaptable services. Proactive
adaptation of such systems allows changing the service and the context
based on prediction. However, the definition of the context is still
vague and not suitable to prediction.
In this paper, we discuss and classify previous definitions of context. Then, we present a new definition which allows pervasive systems to understand and predict their contexts. We analyze the essential lines that fall within the context definition, and propose some scenarios to clearify the purpose of our approach.
