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位置和移动性进行，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应用程序所需要的数据管理，它超越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和固定主机上复制的移动数据，以及(2)用于处理产生和访问这些移动数据的事务和活动。考虑到移动主机上固有的资源限制以及断开连接并不一定意味着断开连接的机器出现故障这一事实，恢复和断开连接管理以集成的方式进行处理。本研究结合了基于ACTA扩展交易框架的理论调查和实证评估，将为移动和无线分布式计算机系统提供一个实验平台。通过考虑开发移动数据管理协议的实际问题，本研究将促进诸如支持远程诊断或手术干预的远程医疗等重要应用的发展。即将建立的实验实验室也将为本科生提供实践经验，使他们接触到研究过程本身，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.
