移动环境和设备的限制，给移动开发带来了挑战。移动中间件能够为移动应用开发提供了一个很好的基础平台。叙述了自适应机制在中间件层实现的必要性，分析了传统面向对象中间件应用在移动计算环境中的不足。根据移动应用的需求，提出了一个基于上下文感知的移动中间件体系结构。关键词：中间件；移动计算；上下文感知；自适应；移动中间件设计Abstract: The limitation of mobile environment and devices bring challenges to mobileapplication development. Mobile middleware can provide an efficient infrastructure platform.Firstly the necessity of executing adaptation mechanism in middleware layer was described. And then the disadvantage of using traditional object-oriented middleware in mobile domain was analyzed. At last, according to the requirement of mobile application, a middleware infrastructure based on context aware was presented.Key words: middleware; mobile computing; context aware; adaptation; mobile middlewaredesign
