CSR?CSI?SGER: Sensor Systems Technologies for Dynamic Data-Driven Scientific Applications The overall goal of this research project is to develop sensor system middleware and programming support that will enable distributed networks of sensors to function, not only as passive measurement devices, but as intelligent data processing instruments, capable of data quality assurance, statistical synthesis and hypotheses testing as they stream data from the physical environment to the computational world. Specifically, this exploratory project will address the following research components: investigate a programming system that will support the development of in-network data processing mechanisms, and will enable scientific/engineering applications to discover, query, interact with, and control instrumented physical systems using semantically meaningful abstractions; investigate services for active in-network data processing that will generate appropriate data/information to drive novel algorithms for modeling, interpretation and decision making, as well as algorithms for information acquisition with dynamic qualities and properties from streams of data from the physical environment, and explore how applications can control data acquisition; and investigate middleware services for the application-driven dynamic management of sensor systems for physical instrumentation, including overlay sensor system runtime management and adaptation, computation/communication/power tradeoffs and dynamic load-balancing. The proposed research activities will be performed driven and validated with two different applications: (1) subsurface modeling and geo-system management and control and (2) contaminant management and geo-system remediation. A key deliverable of this research will be an experimental infrastructure that will build on the NSF Orbit wireless sensor network testbed at Rutgers University and develop the software infrastructure that will enable scientists and engineers to experiment with different aspects of dynamic data-driven application systems (DDDAS), and will design this simulation environment in close collaboration with the 2 different application groups so that it closely emulates their DDDAS requirements.

CSR？CSI？SGER：用于动态数据驱动科学应用的传感器系统技术本研究项目的总体目标是开发传感器系统中间件和编程支持，使分布式传感器网络不仅作为被动测量设备，而且作为智能数据处理工具发挥作用，能够在将数据从物理环境传输到计算世界时提供数据质量保证、统计合成和假设测试。具体地说，这个探索性项目将涉及以下研究组成部分：调查将支持开发网络内数据处理机制的编程系统，并将使科学/工程应用程序能够使用有语义意义的抽象来发现、查询、交互和控制仪表化物理系统；调查将生成适当数据/信息以驱动用于建模、解释和决策的新算法的主动网络内数据处理服务，以及用于从物理环境的数据流中获取具有动态质量和属性的信息的算法，并探索应用程序如何控制数据获取；研究了用于物理仪器传感器系统应用驱动的动态管理的中间件服务，包括覆盖传感器系统运行时管理和适配、计算/通信/功率权衡和动态负载平衡。拟议的研究活动将通过两种不同的应用进行驱动和验证：(1)地下建模和地球系统管理和控制；(2)污染物管理和地球系统补救。这项研究的一个关键成果将是一个实验基础设施，它将建立在罗格斯大学的NSF Orbit无线传感器网络试验台上，并开发软件基础设施，使科学家和工程师能够试验动态数据驱动应用系统(DDDAS)的不同方面，并将与两个不同的应用小组密切合作设计这个模拟环境，以便它能够密切模拟他们的DDDAS需求。
