CAREER: Towards Proactive and Collaborative Mobility-Aware Edge Intelligence

物联网(IoT)网络规模和数据量的显著增长为数据分析和学习提供了诱人的机会，以支持决策并获得科学发现和创新。多路访问边缘计算(MEC)使物联网设备能够将其延迟敏感型资源密集型任务分流到附近的边缘设备。然而，用户移动性带来的时空不确定性给MEC在提供可预测的性能和保证的服务质量(Qos)方面带来了最具挑战性的障碍。此职业计划的研究任务是开发主动和协作的移动性感知MEC系统的基础，以提高物联网应用的服务质量，最大限度地减少数据移动，并优化整体系统性能。该项目关注移动环境中移动性的方方面面，包括以下场景：(I)移动物联网设备/边缘设备根据自己的决定移动;(Ii)系统利用移动边缘设备移动到特定需求区域;以及(Iii)系统激励移动物联网设备移动以获得更好的服务质量。为了支持项目使命，该项目将设计一种新的数据驱动方法来推断导致违反服务质量的重要移动模式，并将基于集成的社区检测和多维流动方法开发独特的主动卸载和服务部署方法。本项目将研究基于主动学习的方法的设计，以根据可能导致违反服务质量的任何更改自主执行操作。该项目将促进移动边缘设备的动态放置和重新定位，以提供低延迟边缘服务。该项目还将调查对具有位置灵活性的物联网设备和边缘设备提出位置更改建议的影响，并将设计反向拍卖机制和双边机制，以平衡系统负载并进一步提高响应时间。该职业项目将整合教学、研究和外联活动，通过提供有意义和令人兴奋的学生参与和微调的指导，扩大对系统研究的接触，并提高学生留存率和代表性不足的学生的代表性。拟议的研究计划将解决为移动物联网应用的实时处理需求构建移动性感知MEC系统的技术挑战，以实现云到物的连续体上的边缘智能，并将丰富先进计算系统设计的科学知识。协作移动边缘设备的可用性将提高终端用户的边缘服务质量，并将支持更多今天尚不可能实现的创新应用。拟议的教育计划将教育学生关于MEC的现代概念，并为他们进入相关职业做好准备。该项目的大量材料将以教程、讲座、出版物、代码、数据集和测试台的形式在网上公开提供。该项目由教师早期职业发展计划(Career)和既定的激励竞争性研究计划(EPSCoR)共同资助。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The significant increase in both IoT (Internet of Things) network size and data volume opens up attractive opportunities for data analysis and learning to support decision making and derive scientific discovery and innovations. Multiaccess Edge Computing (MEC) enables IoT devices to offload their delay-sensitive resource-intensive tasks to nearby edge devices. However, spatio-temporal uncertainties due to user mobility bring the most challenging obstacles for MEC in providing predictable performance and guaranteed Quality-of-Service (QoS). The research mission of this CAREER proposal is to develop foundations of proactive and collaborative mobility-aware MEC systems to improve QoS for IoT applications, minimize data movement, and optimize the overall system performance. This project focuses on all aspects of mobility in MEC, which include these scenarios: (i) mobile IoT devices/edge devices move as their own decisions; (ii) the system makes the use of mobile edge devices to move to a specific demand area; and (iii) the system incentives the mobile IoT devices to move to receive better QoS. In support of the project mission, this project will design a novel data-driven approach to infer vital mobility patterns leading to QoS violations, and will develop a unique proactive offloading and service deployment approach based on an integrated community detection and multidimensional flow approach. This project will investigate the design of a proactive learning-based approach to act autonomously based on any changes that may lead to QoS violation. This project will facilitate dynamic placement and relocation of mobile edge devices in providing low-latency edge services. This project will also investigate the effects of suggesting location changes to IoT devices and edge devices with location flexibility, and will design a reverse-auction mechanism and a two-sided mechanism to balance the system load and further improve response time.This CAREER project will integrate teaching, research, and outreach activities to broaden exposure to systems research and increase student retention and representation of underrepresented students by providing meaningful and exciting student involvement and finely-tuned mentorship. The proposed research plan will address the technical challenges in building mobility-aware MEC systems for realtime processing demands of mobile IoT applications to enable edge intelligence along the cloud-to-thing continuum and will enrich the scientific knowledge of advanced computing system design. The availability of collaborative mobile edge devices will improve the quality of edge services for end-users and will empower many more innovative applications that are simply not yet possible today. The proposed educational plan will educate students on modern notions of MEC and prepare them for related professions. A substantial quantity of the materials of this project will be made publicly available online in the form of tutorials, talks, publications, codes, datasets, and testbeds.This project is jointly funded by the Faculty Early Career Development Program (CAREER) and the Established Program to Stimulate Competitive Research (EPSCoR).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.
