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

该奖项通过高性能无线研究和教育网络(HPWREN)支持Hans-Werner Braun在加州大学圣地亚哥分校的研究，高性能无线研究和教育网络(HPWREN)是NSF资助的无线高带宽网络基础设施，始于2000年，一直在不断发展，包括在难以到达的地区的各种研究和教育应用，以及第一响应者和公共安全活动。该网络主要在南加州偏远和崎岖的地区运行，从太平洋上的圣克莱门特岛，经加州海岸，到内陆山谷，再到高山，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点。许多科学学科和教育活动都受益于该网络，包括一些由国家科学基金会资助的项目。如果没有这种高速数据网络连接，这些项目的许多研究目标将很难实现，甚至有几个甚至不可能实现。智能价值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，使人们能够了解否则必须获得的环境条件。实时数据可以增加对一系列科学概念的了解和理解，例如对地球生态系统的严重影响，以及对整个宇宙中瞬变事件的跟踪。重大成就的例子包括对具有不同流量特征的网络工作负载的研究，以及Palomar天文台的重大发现，在野地火灾期间提供宝贵的帮助，以及扩大美洲原住民与主流人群联系的社会方面，这种联系带来了重大的教育好处。这项更新提案的两年工作范围是三倍。(2)继续研究高功能无线网络基础设施的服务质量考虑因素，以及(3)评估向更可持续的基础设施目标过渡的策略。广泛影响该项目以网络研究为中心，也是促进各种科学学科和教育活动的网络基础设施。同时与多个机构合作。HPWREN的合作者，连同这个项目的NSF支持，对整个环境进行了大量的投资，包括通过使用许多不同范围和规模的项目来增强它。HPWREN的具体研究正在工作量分析、性能评估以及主干和接入链路服务质量以及基于政策的例行实施和试验等领域进行。网络影响领域的研究也在继续-体贴的智能传感器，根据本地确定的事件转发数据，而不是连续转发。该网络目前的稳定性和可靠性是其多年发展努力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进行大量投资，实施主干链路分集，以及将高流量链路升级到155 Mbps的容量。还计划进行进一步的改进，例如一条通往Palomar天文台的单独的45 Mbps路径，使其总带宽达到200 Mbps的全双工链路。延续HPWREN的基础设施和研究环境是该项目的一个目标。

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.
