Reasoning Mechanism Based on the Demspter-Shafer Evidence Theory for Pervasive Context Aware Computing Application

With the advancement of pervasive computing and the wide deployment of wireless communication, there is an increasing demand for the context aware computing application. This paper presents a context aware application model for the easy creation and flexible deployment of the context aware application. Specially, we apply the Demspter-Shafer Evidence Theory(DSET) into the reasoning mechanism of this model and just based on this theory we construct the inferencer which is the core component for this proposed model. And in the end we design an application scenario to demonstrate the basic operation of the Inferencer.
