| 摘 要： | 设计和实现了普适计算中觉察上下文应用的开放式支撑环境———OCAenv.提出并探索了一系列的相关关键技术:觉察上下文功能层次模型、主体-类型模型、上下文服务统一模型、动态绑定机制、交易器联邦路由机制;设计了一个基于中间件的觉察上下文支撑环境OCAenv,包括pvcwCORBA、上下文服务、发现服务和动态绑定层.在以上工作的基础上,开发了一个觉察上下文应用WiW2,检验了原型OCAenv的各项特征.通过演示系统WiW2证明了本方案的实用性和开放性.

| Abstract: | An open infrastructure for context aware in pervasive computing,named OCAenv is implemented.A series of key technologies are studied on,which includes the layered function model of context-aware,subject-type model,unified context service model,dynamic binding mechanism,routing mechanism in trader federation.OCAenv is designed and implemented.Its main components include pvcwCORBA,context-aware object service,discovery service and dynamic binding layer.A context-aware application,named WiW2 is implemented.The outstanding applicability and openness of OCAenv is verified through the WiW2. |
