The behavior of pervasive applications depend not only on their internal state and user interactions
but also on contexts sensed during their execution. In this work, we present a collaborative
context-aware service platform based on hybrid context management model (enhanced CoCA). It
performs reasoning and decisions based on context data, context semantics, and related rules and
policies. Such data is organized into a hybrid context management model (HCoM). The platform
also introduces a neighborhood collaboration mechanism to facilitate peer collaboration in order to
share their resources. We have developed an initial prototype of the platform. Our preliminary test
shows that the platform is a promising data independent development environment for pervasive
context-aware applications and it possesses good standard of scalability.
