EAGER: Distributed Data-Sharing for Fast Response and Decision Support

智慧城市的愿景是以其收集、管理和使用数据的能力为基础的。然而，数据访问仍然是城市机构、公共机构和社区利益相关者面临的一个根本挑战。该项目通过实施一个新的数据访问框架，支持数据共享的范式转变，该框架允许用户在现场共享数据访问，而不是四处发送数据副本。该项目建立在新的数据访问范式的基础上，部署城市数据访问网络（City-DAN），以支持城市管理者及时访问重要数据，以便快速决策和响应。City-DAN首先在越南胡志明市进行试点，然后扩展到其他东盟城市。 这项活动是为了响应NSF亲爱的同事信，支持通过美国东盟（东南亚国家联盟城市）智慧城市伙伴关系与NSF和美国国务院合作，将研究转移到城市。 研究团队（弗吉尼亚大学）与胡志明市的利益相关者（包括城市管理者、部门和社区组织者以及越南国立大学-国际大学）密切合作，将技术转化为实践。拟议的分布式点对点数据访问框架代表了下一代数据生态系统的宏伟愿景。该项目建立了一个基础数据平台，通过解决数据完整性、来源、控制和及时访问等问题来支持智慧城市。该项目利用独特的部署机会，追求一个充满活力的研究议程上的网格计算。具体的研究领域包括先进的网络基础设施，网络安全，网络和持久性标识符。该项目将特别关注基础设施不可靠和保证级别（身份验证）基线较弱的背景下的身份和访问管理（IAM）。该项目将研究新的方法来提高可靠性，同时平衡透明度和QoS。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The vision of a smart city is underpinned by its ability to collect, manage, and use data. However, data access remains a fundamental challenge across city agencies, public institutions, and community stakeholders. This project is championing a paradigm shift in data sharing by implementing a new data access framework that allows users to share access to data in-situ instead of sending copies of data around. This project builds on the new data access paradigm to deploy a city Data Access Network (City-DAN) to support city managers get timely access to important data for fast decision and response. City-DAN is piloted first in Ho Chi Minh City, Vietnam and then scaled to other ASEAN cities. This activity is in response to NSF Dear Colleague Letter Supporting Transition of Research into Cities through the US ASEAN ((Association of Southeast Asian Nations Cities) Smart Cities Partnership in collaboration with NSF and the US State Department. The research team (University of Virginia) is working closely with stakeholders in Ho Chi Minh City including city managers, departments, and community organizers as well as Vietnam National University – International University to transition technology into practice.The proposed distributed, peer-to-peer data access framework represents an ambitious vision of the next generation data ecosystem. This project establishes a foundational data platform to underpin smart cities by addressing issues of data integrity, provenance, control, and timely access. This project takes advantage of the unique deployment opportunity to pursue a vibrant research agenda on grid computing. Specific research areas include advanced cyber infrastructure, cybersecurity, networking, and persistent identifiers. This project will especially focus on identity and access management (IAM) in the context of unreliable infrastructure and weak level-of-assurance (identify proofing) baselines. The project will examine new approaches for enhancing reliability while balancing with transparency and QoS. Lessons learned also can be adopted to advance the smart and connected community research community in the US and other countries.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
