A Petri-Net Based Context-Aware Workflow System for Smart Home

Workflow model has been successfully applied to the traditional computing environment. Currently, there are many studies trying to apply workflow to ubiquitous computing environment. In ubiquitous computing environment, a service must be based on the user's context information to be executed. Now, however, there is no workflow system has a pervasive computing environment to support context-aware services. We intend to establish a pervasive computing environment which can be used in smart home workflow model. The system model based on the user's current context information to provide services for the user's current context, and use the Petri net model tools for workflow modeling. Thus parallel to the workflow model and to visualize formal verification correctness. Workflow using Petri net model which is a graphical and mathematical sets in one, is an ideal tool for formal modeling. We intend to apply the system model to a specific smart home, to validate the correctness of our proposed system.
