Context-aware system modeling and simulation based on Petri net
基于Petri网的情境感知系统建模与仿真

The context-aware system has a highly demand in the context information utilization and the service diversity, but traditional methodologies are incapable of modeling and simulating the context-aware applications in a dynamic environment. This paper proposed a context-aware timed color Petri net by extending the traditional Petri net and took the CPN Tools as the simulation tool to verify and simulate the model, in order to find out the shortage of the context-aware system designed and improved it. The described methodology had been successfully proved by the case of smart assisting system for dementia.
