In the context-aware computing domain, context infrastructure is used to lower the development effort and maintenance cost of context-aware applications. The conventional context infrastructures are tailored with specific service scenarios in the application environment. Once the conventional context infrastructure needs to be deployed into another environment, the cost on perfective maintenance is huge. This work claims the reason is, in conventional context infrastructure lifecycle, only development phase and usage / maintenance phase are considered, but the deployment phase is ignored. By analyze the problems a context infrastructure needs to solve, we can redistribute problems into development phase and deployment phase separately. This results a decoupling of general context-awareness problem from deployment phase problems. A layered conceptual model is proposed as the kernel of adaptive context infrastructure. The layered conceptual model not only solves the general context-awareness problem, but also left well-designed configuration / tuning points for deployment. Based on the layered conceptual model, we can development an adaptive context infrastructure that can be deployed in different environment with lower effort.
