移動環(huán)境和設(shè)備的限制，給移動開發(fā)帶來了挑戰(zhàn)。移動中間件能夠為移動應(yīng)用開發(fā)
提供了一個很好的基礎(chǔ)平臺。敘述了自適應(yīng)機制在中間件層實現(xiàn)的必要性，分析了傳統(tǒng)面向?qū)ο笾虚g件應(yīng)用在移動計算環(huán)境中的不足。根據(jù)移動應(yīng)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(jié)構(gòu)。

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
