RAPID: Assessing the Impact on Operational Mobile Networks in the Face of COVID-19 Public Health Crisis

该项目旨在测量和诊断国家4G/4. 5G移动的网络在面对COVID-19大流行时的性能和可靠性。其目标是在这场公共卫生危机期间，在不对基础设施进行重大升级的情况下，满足评估运行中的移动的网络、揭示技术问题、了解其紧迫挑战并提出补救措施的迫切需要。该项目利用了一种新的设备上测量方法。它利用近年来在构建软件工具和进行大规模测量方面的广泛努力来进行五个重点。首先，它计划进行一项纵向研究，以量化美国运营商网络在面对COVID-19时的性能变化，并分析紧迫的技术挑战背后的原因。其次，它计划设计和评估数据驱动的设备端解决方案，以提高数据性能，而无需任何基础设施升级。第三，它计划描述和诊断在这段时间内可能更经常发生的故障。第四，它计划评估先前研究中披露的安全问题，并研究可能的攻击如何变化。第五，计划开放数据，方便社区研究人员为长期网络创新赋能。该项目将有助于评估新冠肺炎疫情期间移动的用户体验。从长远来看，该项目收集和发布的开放数据集将使数据驱动的软件解决方案能够有效地利用增强的网络功能，并加速移动的网络研究社区的5G创新。软件工具和收集的数据将在http://milab.cs.purdue.edu/上提供。这个奖项反映了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。

This project proposes to measure and diagnose performance and reliability of the national 4G/4.5G mobile networks in face of COVID-19 pandemic. The objective is to meet the immediate need of assessing operational mobile networks, unveiling technical issues, understanding their pressing challenges, and proposing remedies without major infrastructure upgrade during this public health crisis. The project exploits a novel on-device measurement approach. It leverages extensive efforts in building software tools and conducting large-scale measurement in the recent years to conduct five thrusts. First, it plans to conduct a longitudinal study to quantify how performance of US carrier networks change in face of COVID-19 and analyze why behind the pressing technical challenges. Second, it plans to design and assess data-driven device-side solutions to boost data performance without any infrastructure upgrade. Third, it plans to characterize and diagnose failures which likely occur more often during this period of time. Forth, it plans to assess security issues disclosed in prior studies and examine how possible attacks vary. Fifth, it plans to open up data and facilitate researchers in the community to empower long-term network innovations.The project will help assess the mobile users' experience during the COVID-19 pandemic. In the long term, open datasets collected and released by this project will empower data-driven software solutions to efficiently utilize enhanced network capabilities and accelerate 5G innovations in mobile network research community.The software tools and collected data will be available at http://milab.cs.purdue.edu/. The repository will be maintained for at least five years.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.
