摘　　要：为了提高普适计算系统的开发效率,设计了一个基于OSGi框架的动态普适计算中间件模型.该中间件模型以OSGi框架为基础,建立移动管理器管理用户和服务的移动,利用上下文管理器来管理上下文,动态调整自己的行为,支持上下文感知应用.通过标准的接口实现各种异构普适设备间的互操作性.实验结果表明该中间件能够满足通用普适计算环境的要求,对于普适计算系统的开发具有一定的借鉴意义.In order to improve development efficiency of pervasive computing system, an OSGI-based framework middleware for pervasive computing is designed. The middleware is implemented under the OSGI framework. The mobile manager is designed to manage the mobility of user and service, and context manager is used to manage context and support context-aware application. The middleware has realized interoperation among the heterogeneous ubiquitous devices by applying standard interface technologies. Results of experiment show that middleware is feasible, and satisfies the characteristics and requirements of the pervasive computing environment very well.
