基于普适环境的自适应系统研究

Research on Adaptive System Based on Pervasive Environment

作为新的计算模式,普适计算为应用技术界开辟了一个崭新、宽阔的研究领域。普适计算的目标是无时无处不在而又不可见,具有泛在性、便捷性和适应性的特点,对软件自适应机制提出了新的挑战。针对自适应技术用于普适计算下存在的问题,对自适应技术的体系结构展开研究,提出了一个适用于普适计算环境的自适应中间件模型。力图实现一种能够较好支持普适计算环境的软件基础架构,并通过分布仿真原型系统的实验比较说明该中间件体系结构的执行效率。对自适应系统与自适应策略进行了探讨。

As a new model of computing,pervasive computing inaugurates a whole new and wide field of research for the application and technology kingdom.The aim of pervasive computing is＂everywhere,anytime and invisible＂ computing.Moreover,there are three characters-ubiquitous,convenience and self-adaptive in pervasive environment,thus it brings a new challenge for the scheme of software self-adaptive.To solve the questions of adaptive technology for pervasive computing environments,research on the architecture of adaptive technology is introduced.An adaptive middleware model is presented according to the character of pervasive computing.Aimed to propose a software infrastructure that could meet requirements of pervasive computing and facilitate the development of pervasive applications.Experiments made on the prototype middleware system called＇distributed interactive simulation prototype system＇ showed the middleware architecture.In addition,adaptive system and adaptive strategy are discussed in detail.
