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

提议的设备支持“查询和管理异构和不断发展的分布式数据源”的研究计划。该研究计划研究异构和不断发展的数据库和数据流的鲁棒集成。我们的重点是弹性应用程序，它可以在没有人工干预的情况下适应远程数据源的变化。该研究项目还研究了异构数据和数据流的自主存储和交换。目标是根据查询工作负载、存储能力和数据集或数据流的结构分析实现数据存储和数据交换的调优。我们建议建立一个灵活的测试平台环境，分布式地承载丰富的数据集和数据流。一个具有足够计算和存储资源的主测试平台服务器将模拟一个分布式数据库系统，该系统包含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。我们的测试平台的一个关键特点是传感器和RFID技术组件。我们建议将无线传感器、有源和无源RFID技术作为测试平台的一部分，以便我们能够对传感器基站和RFID读取器生成的实际数据流进行实验。

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.
