II-NEW: An Infrastructure for Scalable Data Dissemination and Query Evaluation in Mobile Environments

该项目正在构建一个名为ScalableSQ的可伸缩移动计算仿真基础设施。随着移动计算的普及，人们越来越需要允许移动用户通过他们的移动设备无处不在地访问数据和处理查询。在过去的十年中，人们一直致力于研究移动计算环境中的空间查询处理和普适数据传播。然而，支持大规模移动计算系统的可扩展数据分发和高效的空间查询处理的研究问题还没有得到很好的探索。该项目的主要目标是设计和开发一个可扩展的数据分发和查询评估基础设施，用于查询、索引和路由数据集，以支持新型移动应用。正在解决的具体研究挑战包括设计高度可扩展的空间查询评估机制、用于加快空中数据访问的广播信道访问界限、用于减少访问延迟和调整时间的有效存储器管理策略、以及用于促进基于数据共享的查询处理的新颖请求路由技术。除了研究，该项目还通过ScalableSQ基础设施向本科生和研究生提供移动计算实践体验，从而使教育受益。此外，私营部门还将在塔斯基吉大学(HBCU)组织讲习班，并与工业伙伴合作，传播该项目的新发现，作为推广活动的组成部分。该项目的成果将作为研究论文和免费提供的工具在项目网站上传播，网址为http://www.eng.auburn.edu/~weishinn/ScalableSQ.html.

This project is building a scalable mobile computing emulation infrastructure named ScalableSQ. With the popularity of mobile computing, there is an increasing need to allow mobile users to access data and process queries ubiquitously through their mobile devices. In the past decade, research efforts have been investigateing spatial query processing and pervasive data airing in mobile computing environments. However, the research issues on scalable data dissemination and efficient spatial query processing for supporting large-scale mobile computing systems have not been well explored. The main objective of this project is to design and develop a scalable data dissemination and query evaluation infrastructure for querying, indexing, and routing datasets to support novel mobile applications. Specific research challenges being addressed include design of highly scalable spatial query evaluation mechanisms, broadcast channel access bounds to speed on-air data accesses, effective memory management strategies to reduce access latency and tuning time, and novel request routing techniques to facilitate data sharing based query processing. In addition to research, this project also benefits education by providing hands-on experience in mobile computing through the ScalableSQ infrastructure to both undergraduate and graduate students. Furthermore, the PIs will organize workshops at Tuskegee University (an HBCU) and collaborate with industrial partners to disseminate new discoveries from this project as the outreach component. The results of this project will be disseminated as research papers and as freely available tools in the project website at http://www.eng.auburn.edu/~weishinn/ScalableSQ.html.
