Abstract
This paper presents a proof-of-the-concept of a novel means to develop in an easy way, to execute In a more pervasive way and to maintain In a more sustainable way context-aware services. The essence of this approach Is the Integration of the policy-based management (PBM) technique and the MDA (model-driven architecture) technique. The presence of policies grants context-aware services the high flexibility and adaptability as their nature, whereas the Introduction of MDA for context-aware service Information model fundamentally solves the Information model puzzle of current PBM. MDA's middleware-neutral feature also benefits the smooth evolution of context-aware services as a kind of software. The preliminary case study has proved the positive feasibility of this approach. © 2005 IEEE.
