摘要
基于移动终端、情境感知以及无线传感器网络的结合需求,提出了一种应用于移动终端的情境感知系统,包括若干无线传感器节点、情境感知及处理终端、应用服务及执行装置等。针对移动电子设备一般都不具备接入无线传感器网络所需功能单元的现状,利用uSD概念为移动终端设计了一个Z igBee通信功能扩展模块,使移动终端能够从无线传感器网络中获取情境信息,并提供相应的情境感知和处理功能。最后,设计了包含位置等信息的情境感知服务演示系统,初步验证了基于uSD的情境感知系统在移动终端上应用的新颖性和有效性。
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.
