A testbed for distributed information systems with sensor and radio frequency identification technology

该设备支持的研究项目《查询和管理异质和不断演变的分布式数据源》。该研究计划研究异质和不断演变的数据库和数据流的稳健集成。我们的重点是能够适应远程数据源的变化而无需人工干预的弹性应用。此外，该研究计划还研究异质数据和数据流的自主存储和交换。其目标是基于查询工作量、存储能力和对数据集或数据流的结构分析来实现数据存储和数据交换的调整。我们建议建立一个灵活的试验台环境，它分布式地托管丰富的数据集和数据流。我们建议，拥有足够计算和存储资源的主试验床服务器将模拟一个分布式数据库系统，其中包括从关系数据仓库到可扩展标记语言(XML)、存储库到Web服务和Web应用程序的数据集。*资源较少的传感器边缘服务器将管理来自外部无线传感器网络和射频识别(RFID)设备的流数据。*我们试验台的一个关键功能是传感器和RFID技术组件。*我们建议包括无线传感器，有源和无源RFID技术作为试验台的一部分，因此我们能够试验由传感器基站和RFID读取器生成的真实数据流。

The proposed equipment support the research program "Querying and Managing Heterogeneous and Evolving Distributed Data Sources".  The research program studies robust integration of heterogeneous and evolving databases and data streams.  Our emphasis is on resilient applications which can adapt to changes in remote data sources without manual intervention.  The research program also studies autonomous storage and exchange of heterogeneous data and data streams.  The objective is to achieve tuning of data storage and data exchange based on query workload, storage capabilities and structural analysis of the data set or data streams.   We propose to build a flexible testbed environment which hosts a rich set of data sets and data streams distributedly.  A main testbed server, that has sufficient computing and storage resource, will simulate a distributed database system consisting of data sets ranging from relational data warehouse to extensible markup language (XML)  repositories to web services and web applications.  A sensor edge server with lesser resource will manage streamed data from external wireless sensor networks and radio frequency identification (RFID) devices.  A key feature of our testbed is the sensor and RFID technology component.  We propose to include wireless sensors, active and passive RFID technology as part of the testbed so we are able to experiment with realistic data streams generated by sensor base stations and RFID readers.
