移動環境和設備的限制，給移動開發帶來了挑戰。移動中間件能夠為移動應用開發
提供了一個很好的基礎平臺。敘述了自適應機制在中間件層實現的必要性，分析了傳統面向對象中間件應用在移動計算環境中的不足。根據移動應用的需求，提出了一個基于上下文感知的移動中間件體系結構。
關鍵詞：中間件；移動計算；上下文感知；自適應；移動中間件設計
Abstract: The limitation of mobile environment and devices bring challenges to mobile
application 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 middleware
