This project tackles the problem of determining the geographic location of Internet hosts from their Internet addresses (the “geolocation problem”). Geolocation is a fundamental problem in computer networking that affects numerous aspects of Internet operation, research, and development. Unfortunately, ample evidence shows that existing geolocation services are prone to errors and inaccuracies, especially when it comes to mapping content provider platforms. Beyond the obvious impact on applications relying on geolocation, these inaccuracies undermine the rigor of any research that utilizes geolocation. This research will develop novel techniques that improve the efficiency and accuracy of geolocation and leverage these techniques to systematically assess the accuracy of influential existing geolocation services. Geolocation commonly involves measuring network delays from a set of “landmarks” (the hosts with known locations) to the geolocation target. By selecting – differently for different targets -- a small number of landmarks from a large pool of candidates, this project attempts to break the dilemma where a large number of landmarks is desired for higher accuracy but leads to scalability limits due to high measurement volumes. Through developing a new geolocation methodology, assessing if its new capabilities could make provably correct geolocation feasible for a substantial fraction of Internet hosts, and evaluating the accuracy of existing geolocation services, this activity will advance our knowledge in the area of Internet host geolocation, a fundamental problem in networking affecting numerous aspects of Internet development.Advancing the state of the art in Internet host geolocation has broad impact through benefiting any applications and research that relies on geolocation. To the extent that it will show that provable geolocation is practical, this project will transform how networking research relying on geolocation is done, by allowing rigorous reasoning about host locations. Datasets containing active measurements, as well as software artifacts, produced in the course of this project will be made publicly available. The project will significantly enhance undergraduate and graduate education at CWRU and facilitate its ongoing efforts in broadening participation of underrepresented sections of the population in computer science.All the data (anonymized when needed) and relevant software artifacts the project produces will be made available through the project website at http://engr.case.edu/rabinovich_michael/geolocation. The content itself will be stored at external public repositories such as github (github.com) and OSF (osf.io), while the project website will provide links to the content along with its description. This will be kept available for at least 5 years after the project completion.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.

该项目处理从因特网主机的因特网地址确定其地理位置的问题（“地理位置问题”）。 地理定位是计算机网络中的一个基本问题，它影响着互联网运营、研究和开发的许多方面。不幸的是，大量证据表明，现有的地理定位服务容易出现错误和不准确，特别是在地图内容提供商平台方面。除了对依赖地理定位的应用程序的明显影响外，这些不准确性还破坏了任何利用地理定位的研究的严谨性。 这项研究将开发新的技术，提高地理定位的效率和准确性，并利用这些技术来系统地评估有影响力的现有地理定位服务的准确性。 地理定位通常涉及测量从一组“地标”（具有已知位置的主机）到地理定位目标的网络延迟。 通过选择-不同的目标-少量的地标从一个大池的候选人，该项目试图打破困境，大量的地标是需要更高的精度，但导致可扩展性的限制，由于高测量量。 通过开发一种新的地理定位方法，评估其新功能是否可以使可证明正确的地理定位对相当一部分互联网主机可行，并评估现有地理定位服务的准确性，这项活动将推进我们在互联网主机地理定位领域的知识，这是网络中的一个基本问题，影响着互联网发展的许多方面。通过使任何依赖于地理定位的应用和研究受益，产生广泛的影响。在某种程度上，它将表明可证明的地理定位是可行的，该项目将通过允许对主机位置进行严格推理来改变依赖于地理定位的网络研究的方式。在该项目过程中产生的包含主动测量的数据集以及软件工件将公开提供。该项目将大大提高CWRU的本科生和研究生教育，并促进其正在进行的努力，扩大人口中代表性不足的部分在计算机科学的参与。所有数据（需要时匿名）和项目产生的相关软件工件将通过项目网站http://engr.case.edu/rabinovich_michael/geolocation提供。内容本身将存储在外部公共存储库中，如github（github.com）和OSF（osf.io），而项目网站将提供内容的链接沿着及其描述。 该奖项将在项目完成后至少保留5年。该奖项反映了NSF的法定使命，并且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。
