ITR/IM+AP+SI+PR: Exploring the Environment in Time: Wireless Networks & Real-Time Management

0121726或该项目寻求整合地球科学和信息技术领域的不同努力，以开发一种现代数据收集和整合的模式方法。方法是在现有传感器网络和无线通信的基础上开发支持未来研究所需的硬件和软件，并为应急反应、知情决策、外联和教育以及加强科学发现提供信息。特别是，现有的南加州科学和教育无线网络将沿着海岸从圣地亚哥延伸到圣巴巴拉，并延伸到海峡群岛以外的海洋。由于南加州对来自塞拉积雪的水源的依赖，以及这种水源对气候的依赖，我们将把网络扩展到约塞米蒂国家公园。使用这个试验台，我们将展示无线网络对实时收集和传输环境传感器数据的要求和用途。将整合多学科数据集(例如地震、洋流、水文气象和生态学)，以促进我们对南加州和远离海岸的海岸、海洋、河岸和陆地地球物理现象和生态系统的理解和管理。这种集成必须开发的软件工具还不存在，尽管可用的原型系统有限。特别是，对象环缓冲区(ORB)中用于将学科数据收集到虚拟ORB(VORB)中的现有概念将被扩展，以管理到多个场传感器的多个连接。这些VORB不仅将向多个用户实时提供数据，还将提供与档案ORB和更传统的数据库的接口。这些交互中的许多都将通过XML包装器进行中介，这将为数据发现提供基础。将开发一个基于规则的可编程接口，以动态重新配置和优先处理来自这多种传感器网络的数据捕获和分析。随着网络速度的提高和数据量的增长，这种方法应该是可扩展的，很可能是几何级数的增长。

0121726 OrcuttThis project seeks to integrate disparate efforts in both the Earth sciences and information technology to develop a model approach for modern data collection and integration. The approach is to build upon existing sensor networks and wireless communications to develop the hardware and software needed for supporting research of the future and to make information available for emergency response, informed decision-making, outreach and education, and enhanced scientific discovery. In particular the existing southern California scientific and educational wireless network will be extended along the coast from San Diego to Santa Barbara and to the oceans beyond the Channel Islands. Because of southern California's reliance on water from the Sierra snow pack and the dependence of this source of water on climate, we will extend the network to include Yosemite National Park.Using this test bed the requirements and utility of wireless networks for collecting and streaming environmental sensor data in real-time will be demonstrated. Multidisciplinary data sets (e.g. earthquake, ocean current, hydrometeorological, and ecological) will be integrated to advance our understanding and management of coastal, ocean, riparian, and terrestrial geophysical phenomena and ecosystems in Southern California and well off shore. The software tools which must be developed for this integration do not exist, although limited prototype systems are available.In particular, existing concepts in object ring buffers (ORB) for collecting disciplinary data to virtual ORBs (VORB) for managing multiple connections to multiple field sensors will be extended. These VORBs will not only provide data to multiple users in real time, but will provide interfaces with archival ORB and more traditional databases. Many of these interactions will be mediated through XML wrappers which will provide the basis for data discovery. A rule-based programmable interface will be developed to dynamically reconfigure and prioritize data capture and analysis from this multiplicity of sensor networks. This approach should be scalable as network speeds increase and data volumes grow, likely geometrically.Funding is provided under the Information Technology Research Initiative.
