CAREER: Developing Pragmatic Mobile Data Management Systems

计算机和电信技术的进步使网络通信能够从任何地点和移动性，这将导致新的协作数据库应用。本研究的重点是这些新的移动的应用程序所需的数据管理，这超出了传统的分布式数据库管理。具体而言，其目标是开发适当的协议（1）用于管理通过低带宽和脆弱的无线网络连接在移动的和固定主机上复制的移动的数据，以及（2）用于处理产生和访问这些移动的数据的事务和活动。考虑到移动的主机上的固有资源限制以及断开连接不一定意味着断开连接的机器的故障的事实，以集成的方式接近恢复和断开连接管理。本研究结合了理论研究，建立在ACTA扩展的交易框架，和实证评估，这将导致一个实验平台的移动的和无线分布式计算机系统。通过考虑实用的问题，在开发协议的移动的数据管理，这项调查将促进发展等重要的应用，如远程医疗，支持远程诊断或手术干预。即将建立的实验室还将为本科生提供实践经验，让他们接触研究过程本身，从而鼓励他们发展成熟的科学思维。

Advances in computer and telecommunication technologies enable network communication from any location and mobility that will lead to new collaborative database applications. This research focuses on data management demanded by these new mobile applications, that extends beyond the traditional distributed database management. Specifically, its goal is to develop appropriate protocols (1) for the management of mobile data replicated on both mobile and stationary hosts over low-bandwidth and tenuous wireless network connections, and (2) for the processing of transactions and activities that produce and access these mobile data. Given the inherent resource limitations on a mobile host and the fact that disconnections do not necessarily imply the failure of the disconnected machine, recovery and disconnection management are approached in an integrated manner. This research combines both theoretical investigation, building on the ACTA extended transaction framework, and empirical evaluation that will result in an experimental platform for mobile and wireless distributed computer systems. By considering t he pragmatic issues in developing protocols for mobile data management, this investigation will facilitate the development of such important applications as telemedicine that support remote diagnostics or surgical interventions. The experimental laboratory to be established will also provide hands-on experience for undergraduate students exposing them to the research process itself, thereby encouraging their development of mature scientific thinking.
