【摘要】 普适计算为我们的基础研究与技术应用提供了一个崭新、宽广的研究领域，它是一种全新的计算模式。普适计算可以实现用户获得计算的随时随地性并且对用户隐形，具有便捷性、普适性和能够适应环境变化性的特点。随着普适计算的出现，它在很多研究场合与应用场合都产生了翻天覆地的变化。本文介绍了中间件技术的设计思想及其分类，分析了中间件技术在普适环境下的研究背景与研究现状。研究了几种典型适应普适计算环境的中间件技术，它们对本论文研究普适环境中动态配置中间件（UCDAM）模型具有重要的指导意义。本文在中间件技术研究的基础上，提出了普适计算中间件技术的体系结构，给出了符合普适计算特点的动态配置中间件（UCDAM）的设计思想，设计了面向普适计算的动态配置中间件（UCDAM）模型，并分析了此UCDAM模型的系统原理，模块组成，实现过程和资源服务等，此模型的实现符合普适计算的特征需求。本文针对自适应技术在普适计算环境下的应用，对自适应技术的体系结构进行深入研究，设计了一种基于动态配置中件间的自适应策略与算法。本文实现了一种可以较好支持普适计算环境的UCDAM模型，并且通过基于UCDAM的无线传感器网络以及数据交换平台的实验验证了该中间件模型的可行性。更多还原

【Abstract】 As a new model of computing, pervasive computing inaugurates a whole new and wide field ofresearch for the basic research and technology application. The aim of pervasive computing is"everywhere, anytime and invisible" computing. Moreover, there are three characters-ubiquitous,convenience and self-adaptive in pervasive environment. However it is changing tremendously inreseach and applications of aspects accompanied by the emergence of the pervasive computing.In this thesis, introducing the technical challenges faced by middleware research under pervasivecomputing environment, analyzing the study background and current research state of pervasivecomputing and middleware technology. Studying some kinds of typical middleware which adapted topervasive computing environment, they were very important for designing the middleware of dynamicallocation.On the base of researching middleware technique, it proposes architecture of the pervasivecomputing middleware technique. It presents the design idea that a middleware of dynamic allocationshould acquire, on the demand of the pervasive computing, meanwhlle it designs the model of themiddleware for pervasive computing, of which it makes a analysis about the principle of the systematicframe, module, realization of the process and resource service. And finally it basically can meet theneeds of pervasive computing.To solve the application of adaptive technology for pervasive computing environments, researchon the architecture of adaptive technology is introduced. Adaptive system and adaptive strategy aredesigned in detail.We aimed to propose a model called ‘UCDAM’ that could meet requirements of pervasivecomputing and facilitate the development of pervasive applications. Experiments made on theprototype middleware system called ‘wireless sensor network system based on UCDAM’ and ‘dataexchange platform’ showed the middleware architecture.更多还原
