【摘要】 当今时代,计算机已经进入人类生活的各个领域。计算机在人们日常生活中的实际地位,早已不再是一种供人类使用的简单工具。在很多情况下,计算机成了人们生活和工作不可缺的部件,因此人们必须不断转换思路和使用习惯以适应计算机的发展变化。 随着计算机技术的发展和互联网的普及,这个问题变得日益明显。人们开始考虑计算机和网络应该是什么样子,应该如何为人类服务,于是普适计算的思想便应运而生了。普适计算的目标是通过使计算机融入人们周围的物理环境来增强计算机的功能和影响,同时,计算机对普通用户而言却是完全透明的。 本文从普适计算环境出发,在研究传统应用模型的基础上,提出了普适计算环境下的应用模型,然后就该模型中涉及到的家庭网络接入,家庭网关体系结构和服务管理框架三个关键技术分别做了研究,提出了基于SSP和VPN的安全接入方案;提出了家庭网关的体系结构;利用OSGi提供的API实现了服务管理框架原型,并通过创建一个简单的Bundle来验证框架实现的可应用性。 本文的核心部分是普适计算应用模型、家庭网络接入技术、家庭网关体系结构、服务管理框架原型实现,在研究过程中,作者的主要贡献是: 1.提出了普适计算环境下的应用模型; 2.提出基于SSP和VPN的家庭网络接入方案; 3.提出了家庭网关的体系结构设计方案; 4.根据OSGi提供的API实现了服务管理框架原型。 在研究期间,作者参加了上海广电集团SVA-IBM实验室的iHome项目,进行了普适计算研究,在国内核心刊物发表学术论文1篇。

【Abstract】 Today, computers have come into every corner of human life. Computers are not simple tools any more. In most cases, they are core components of our daily life. So we have to change our mind to adapt to them.With the development of computer technology and Internet, this problem becomes serious. People begin to think what computer and network should be, how they can work for us, thus the thought of pervasive computing conies into mind. The aim of pervasive computing is to enhance the function and influence of computers by embedding them into physical world around us. At the same time, they are transparent to end users.This thesis begins with pervasive computing environment. Then an appropriate application model is put forward on the research work of traditional application models. Then the key elements of the model , Internet connection, service gateway architecture, service management framework, are discussed individually. A SSP-VPN based secure connection solution is proposed. A service gateway architecture is put forward. At last, we implement the prototype of service management framework on the service gateway. A simple Bundle is created to test the practicability of the implementation.The main contributions in this thesis can be concluded as following:1. Put forward an application model of pervasive computing;2. Put forward an SSP-VPN based home network connection solution;3. Put forward a home gateway architecture;4. Implement the service management framework prototype system.. During the research, the author took part in the iHome project raised by SVA-IBM joint Lab, studied pervasive computing technologies, and published one piece of paper in domestic core magazine.
