This paper proposes a context-aware application infrastructure for the easy creation and flexible deployment of the context-aware application. In this infrastructure we introduce the concept of plane to manage the sensors and handle the environment information. Corresponding to the operations in this infrastructure we design a layered structure for the context information and define three kinds of working procedures. In addition, we apply the Demspter-Shafer evidence theory (DSET) to the reasoning mechanism of this infrastructure. Specially, based on combination rule of DSET, we construct the inferencer which is the core component for this infrastructure. In the end, we design an application scenario to demonstrate the operation of the inferencer.
