【摘要】 随着网格技术和嵌入式系统的发展，传统的软件体系结构和提供服务的方式已经不能满足日益普及的移动设备和嵌入式设备的需求，网格计算和普及计算的兴起将改变传统的Client／Server和Client／Cluster结构，形成新的Pervasive／Grid(P／G)体系结构。在这种体系结构之下，客户端是各种各样的无线移动设备，而连在网上的各种服务器将组成单一的逻辑上的网格(Grid)。 网格计算与普及计算之间有着千丝万缕的联系，网格侧重的是把整个因特网整合成一台巨大的超级计算机，实现计算资源、存储资源、信息资源、知识资源、专家资源的全面共享，普及计算侧重人们从互相融合的信息和物理空间中随时随地、透明地获得数字化的服务，将二者结合起来将会给网络的发展注入新的活力，同时也会给传统的网络体系结构提出新的挑战。本文详细研究了网格计算和普及计算的综合及其在移动定位导航系统中的应用。 本文设计并且实现了分层体系结构的移动定位导航系统。首先，将网格计算理论引入到个人导航系统中，开发了GIS服务、交通流预测服务、路径规划服务、GPS定位服务、查询服务；然后，由于Eclipse提供了一个开放灵活的框架，Eclipse技术现在广为流行，基于Eclipse构架的应用越来越多，本文给出了一个基于Eclipse插件开发应用的项目实例；随后，为了解决使用网格系统资源的复杂性问题，我们通过开发网格门户来屏蔽网格资源内部复杂的细节，使用户能以灵活方便的方式访问网格资源；最后，选择JADE-LEAP，并使用它设计和实现出一套基于移动Agent的面向交通领域的通讯中间件，并在普及计算环境下设计和实现了一个功能强大的移动定位导航系统，将其成功部署在nokia6600真机上。更多还原

【Abstract】 With the development of Grid technology and Embeded System, traditional software arthitecture and the way of providing services can not meet the demand of mobile devices and embeded devices. The advent Grid computing and Pervasive computing will change traditional structure of Client/Server and Client/Cluster, which may become Pervasive/Grid(P/G) architecture, under which clients are several of wirless mobile devices. Servers connected to network will construct a single Grid.Grid computing has a close reationship with Pervasive computing. The emphasis of Grid is to change the whole internet into a huge super computer, which will achieve the share of computing resources, storage resources, information resources, knowledge resources, expert resources. Pervasive computing focuses on the smooth and timely attainment of digital service in the space that integrates information with physics. This integration spires the development of network; meanwhile, brings some challenges to the traditional network framework. This essay studies the integration of Grid computing and Pervasive computing and the corresponding application on mobile location based navigation.This essay designs and implements the mobile position-fix navigation system of layered system framework. Firstly, we brings the theory of Grid computing into personal navigation system, and GIS service, forecast service of traffic, the design service of route, GPS position-fix and query service are developed. Then, since Eclipse gives the flexible and open framework, this software is prevalent and more and more service is based on Eclipse framework. This essay describes a project instance of Eclipse Plugin application, and then, in order to solve the complexity of using Grid system source, we develop Grid Portal to shield internal content of Grid source to avoid complicated details. In this way, users can visit Grid source with convenience and flexibility. In the end, by using JADE-LEAP, we design and implement a set of telecommunication components that faces traffic field on the basis of mobile agent; after that, under the circumstance of Pervasive computing, we design and implement a mobile location based navigation system with powerful effect and locate it on nokia6600 mobile phone.更多还原
