Integration and Analysis of Reliable Networking for Remote Science, Education, and First Responders

该奖项支持Hans-Werner Braun在加州大学圣地亚哥分校通过高性能无线研究和教育网络（HPWREN）进行的研究，HPWREN是美国国家科学基金会资助的无线高带宽网络基础设施，起源于2000年，并不断发展，包括各种难以到达的研究和教育应用领域。以及急救人员和公共安全活动。该网络主要在南加州偏远崎岖的地区运行，从太平洋的圣克莱门特岛（San Clemente Island）开始，经过加州海岸，到达内陆山谷和高山，海拔超过8700英尺。然后它穿过沙漠，到达靠近亚利桑那州边境的地方。许多科学学科和教育活动受益于该网络，包括一些nsf资助的项目。如果没有这种高速数据网络连接，许多项目的研究目标将很难实现，有些甚至不可能实现。实时数据的收集是网络最有价值的方面之一，例如部署各种环境传感器，使人们能够了解环境状况，否则就必须获得这些数据。实时数据可以增加对一系列科学概念的认识和理解，例如对地球生态系统的严重影响以及对整个宇宙瞬态事件的跟踪。重大成就的例子包括研究不同交通状况下的网络工作量，以及帕洛马天文台的重大发现，在野火期间提供宝贵的援助，以及扩大美洲原住民与主流人口接触的社会方面，这种接触产生了重大的教育效益。这项更新建议的两年工作范围是三方面的。(5)维护和增强HPWREN网络基础设施，以用于其许多跨学科和多机构的研究、教育和公共安全活动；(2)继续研究功能强大的无线网络基础设施环境中的服务质量考虑因素；(3)评估过渡战略，以实现更可持续的基础设施目标。更广泛的影响在其存在的整个过程中，HPWREN项目在其更广泛的影响方面取得了成功，http://hpwren.ucsd.edu/web网站上的许多新闻更新证明了这一点。该项目以网络研究方面为中心，也为各种科学学科和教育活动提供网络基础设施。同时与多个机构合作。HPWREN的合作者，在这个项目的NSF支持下，对整个环境进行了大量的投资，包括通过增加许多不同范围和规模的项目。具体的HPWREN研究正在工作负载分析、性能评估以及骨干和接入链路服务质量和基于策略的常规实现和实验领域进行。考虑网络影响的智能传感器领域的研究也在继续，它基于局部确定的事件而不是连续地转发数据。该网络目前的稳定性和可靠性是其多年开发工作中吸取的经验教训的直接结果。这包括对fcc许可的频谱无线电系统的重大投资，骨干链路分集的实施，以及将高流量链路升级到155Mbps的容量。进一步的增强计划，例如一个独立的45Mbps路径到帕洛马天文台，使其总带宽达到200Mbps的全双工链路。HPWREN基础设施和研究环境的延续是该项目的目标。

OCI 0944131Hans-Werner BraunUniversity of California at San DiegoAbstractThis award supports Hans-Werner Braun's research at the University of California at San Diego through the High Performance Wireless Research and Education Network (HPWREN) which is an NSF funded wireless high bandwidth cyberinfrastructure, which originated in the year 2000 and has been continually evolving to include various research and education applications in difficult to reach areas, as well as first responder and public safety activities. The network operates in predominantly remote and rugged areas of Southern California, spanning from San Clemente Island in the Pacific Ocean, via the California coast, to the inland valleys and on to the high mountains, reaching an altitude of more than 8700 feet. It then extends across the desert, reaching sites close to the Arizona border. Many scientific disciplines and education activities benefit from the network, including a number of NSF-funded projects. Without access to this high-speed data Networking connectivity, many of these project research objectives would be difficult, and several even impossible to achieve.Intellectual MeritThe collection of real-time data is one of the most valued aspects of the network, such as the deployment of various environmental sensors that enable an understanding of environmental conditions that would be had to obtain otherwise. Real-time data allows for increased knowledge and understanding of an array of scientific concepts such as heavily impact ecological systems on the earth and the tracking of transient events throughout the universe. Examples of significant accomplishments include the research on network workloads with a diverse traffic profile, as well as major discoveries by the Palomar Observatory, providing invaluable assistance during wildland fires, and the social aspects of enlarging Native American contacts with the mainstream populations, with major educational benefits being derived from such contact.The two-year work scope for this renewal proposal is three-fold. (s) maintain and enhance the HPWREN cyberinfrastructure for its many interdisciplinary and multi-institutional research, education, and public safety activities, (2) continue the research on Quality of Service considerations on a highly functional wireless cyberinfrastructure environment, and (3) evaluate transition strategies towards an objective of a more sustainable infrastructure.Broader ImpactThroughout its existence, the HPWREN project has been successful in its broader impacts, as evidenced by many news updates on the http://hpwren.ucsd.edu/web site. This project is centered around network research aspects and also serves as an enabling cyberinfrastructure for various science disciplines and education activities. While partnering with multiple institutions. HPWREN collaborators, alongside this project's NSF support, invested substantially into the overall environment, including by augmenting it with many projects of various scopes and sizes. Specific HPWREN research is ongoing in the areas of workload profiling, performance assessments, as well as backbone and access link Quality of Service and Policy Based Routine implementations and experimentations. Research also continues in the area of network impact-considerate intelligent sensors, forwarding data based on locally determined events, rather than continuously. The current stability and reliability of this network is a direct result of lessons learned in its multi-year development effort. This includes a significant investment in FCC-licensed spectrum radio system and an implementation of backbone link diversity, as well as upgrading of high-traffic links to 155Mbps capacity. Further enhancements are planned, such as a separate 45Mbps path to the Palomar Observatory bringing its aggregate bandwidth to 200Mbps of full-duplex links. Continuation of the HPWREN infrastructure and research environment is an objective of this project.
