摘要: 为了对普适环境下的构件化应用提供支持,扩展传统的构件适配技术,在上下文感知中间件的基础上,提出支持上下文感知的构件适配模型CACAM和构件适配算法CACA,实现对环境、用户上下文的动态感知和重配置。实验结果表明,该模型能够有效地实现普适计算环境下基于上下文感知的构件适配。

Abstract: In order to support component based applications of pervasive environments, traditional component adaptation is extended and a Context-aware Component Adaptation Model(CACAM) is put forward based on component middleware and Context-aware Component Adaptation(CACA) algorithm according to support dynamic awareness and reconfiguration for the context based adaptation. Experimental results show that this model can support the context-aware component adaptation efficiently in the pervasive computing environment.

Key words: pervasive computing, context-aware, component adaptation, middleware, reflection
