The goal of this research is to provide seamless access to the networked computational and information resources from mobile, wirelessly connected systems. Such systems will be an integral component of the National Information Infrastructure (NII). Some of the current obstacles in building such a ubiquitous access system on mobile platforms include their limited compute power, disks, battery life etc., as well as the limited and variable bandwidth of the wireless networks. Moreover, the next generation of radio communication hardware will engender ad-hoc networks which current proxy based mobile access models cannot handle. The approach in this research is to create agent oriented middleware which overcomes the limitations of the mobile hosts as well as wireless networks, and helps integrate them into the high performance computer and communication systems that form the backbone of the NII. The middleware transcodes (multimedia) data streams to enable weakly connected access, and integrates software component based systems to provide computational power to mobile hosts. This allows the systems to create information from available data to respond to queries, which is useful when the queries are in non-trivial domains (e.g. scientific information, electronic commerce). Moreover, the system provides disconnection management, and integrates techniques for cooperative information filtering. The system supports both proxy based and end-end data management approaches and their relative efficacy is compared. It is expected that this work will lead to the development of software systems needed to support mobile information access in complex, real world applications, and allow the NII to handle the diversity of scale presented by mobile clients connected over low bandwidth wireless (ad-hoc) networks to the high bandwidth network backbone and powerful servers. The educational component of this proposal has two aspects. One focuses on creating courses in the area of the proposed research work and training undergraduate and graduate students. The other leverages the proposed research to create adaptive electronic notebooks for science and engineering education which use (existing) courseware, digital libraries and other data repositories. It is expected that the electronic notebook software will be used by non-traditional students in continuing education programs who use low bandwidth dial-in or wireless connections. http://www.cs.umbc.edu/~ajoshi/career/

这项研究的目标是提供从移动无线连接系统对网络计算和信息资源的无缝访问。此类系统将成为国家信息基础设施（NII）的一个组成部分。当前在移动平台上构建这种无处不在的接入系统的一些障碍包括有限的计算能力、磁盘、电池寿命等，以及无线网络的有限且可变的带宽。此外，下一代无线电通信硬件将产生当前基于代理的移动接入模型无法处理的自组织网络。本研究的方法是创建面向代理的中间件，克服移动主机和无线网络的限制，并帮助将它们集成到构成 NII 骨干的高性能计算机和通信系统中。中间件对（多媒体）数据流进行转码以实现弱连接访问，并集成基于软件组件的系统以向移动主机提供计算能力。这允许系统从可用数据创建信息来响应查询，当查询位于重要领域（例如科学信息、电子商务）时，这非常有用。此外，该系统还提供断线管理，并集成了协作信息过滤技术。该系统支持基于代理和端到端的数据管理方法，并对它们的相对功效进行了比较。预计这项工作将导致开发支持复杂的现实世界应用中的移动信息访问所需的软件系统，并允许 NII 处理通过低带宽无线（ad-hoc）连接的移动客户端所呈现的规模多样性。 ）网络到高带宽网络骨干和强大的服务器。该提案的教育部分有两个方面。一是侧重于在拟议的研究工作领域创建课程并培训本科生和研究生。另一个利用拟议的研究为科学和工程教育创建自适应电子笔记本，该笔记本使用（现有）课件、数字图书馆和其他数据存储库。预计电子笔记本软件将供使用低带宽拨入或无线连接的继续教育课程中的非传统学生使用。 http://www.cs.umbc.edu/~ajoshi/career/
