This paper proposed a context-aware system for mobile applications on the demand for the combination of mobile terminals,context-aware and WSN.The proposed system included wireless sensor nodes,context-awareness and processing unit,application services and relating actuators.Due to the fact that mobile electronic devices seldom had the capabilities to access WSN,developed a ZigBee communication expansion module for mobile terminals based on uSD concept.The uSD ZigBee card enabled mobile terminals to get context from WSN so as to provide context-awareness and processing function for users.Then implemented a demonstration system to verify that the application of uSD based context-aware system in mobile terminals is novel and feasible.
