Over the last several decades, we have experienced tremendous growth in the use of cellular telephones and Wi-Fi networks for home and office, as well as emerging wireless technologies geared toward different applications. The massive growth of lightweight hand-held devices used to access wireless networks has resulted in an exponential increase in demand for wireless services and severe wireless spectrum shortage. To overcome these problems, beyond spectrum sharing with licensed users, a new wireless architecture is needed to enhance network coverage, capacity and security. The research objective of this CAREER project is to significantly advance the field of wireless communications, with an expectation of opening transformative research directions, by a) devising a novel generalized wireless virtualization architecture, or Wi-Vi, to provide wireless services to users using Radio-as-a-Service where Wi-Vi architecture will enhance network capacity, coverage, seamless mobility and energy efficiency, and thus be able to support trillions of devices in next generation wireless systems; and b) by extending the scope of the proposed Wi-Vi framework for performance isolation, security and privacy while providing quality-of-service/experience to users in a diverse wireless environment. Moreover, this work will help researchers across many fields understand how wireless communications influences the emerging fields such as smart grid, eHealth, vehicular networks, next generation cellular networks, Internet-of-things, cyber-physical systems and secure cyberspace. The PI will train the next generation of scientists and engineers in the area of next generation wireless networks, and mentor researchers (including minorities and female) at undergraduate and graduate level, as well as inspire K-12 students in science and engineering fields at the early stage of their learning career through hands-on demonstrations. This CAREER project focuses on the design, analysis and evaluation of a Wireless Virtualization (Wi-Vi) framework by combining different wireless resources and infrastructures, beyond spectrum sharing with licensed users, to be used as on-demand service over the network, with the goal of enhancing network capacity, coverage, energy efficiency and security. The PI will develop Wi-Vi architecture using systematic approaches to improve overall network performance. Specifically, the significance of the proposed research includes: 1) development of a generalized wireless virtualization framework that will help meet dynamic demands of wireless users by expanding or shrinking wireless resources of the virtual wireless operators; 2) study and implementation of optimal wireless resource sharing among coverage- and capacity-driven Mobile Virtual Network Operators (MVNOs); 3) development of systematic approaches for base station-level, MVNO-level and user level optimizations and Quality-of-Service (QoS) provisioning; 4) application of wireless virtualization in network security through dynamic network segmentation; and 5) validation and evaluation of the proposed novel techniques through extensive simulations and experiments in NSF-funded cloud testbeds such as ROAR, Chameleon, etc. The CAREER award will have a broad societal impact as wireless networks touch every aspect of our society, and will support enhancement of our national wireless capacity and cybersecurity. This project will impact many emerging areas in which wireless communication has applications - such as smart grid, eHealth, vehicular networks, next generation cellular networks, Internet-of-things, cyber-physical systems and secure cyberspace. The PI will train undergraduate and graduate students by disseminating knowledge to students through new courses and modules on wireless virtualization and next generation wireless networks. Focused efforts will be undertaken to interest underrepresented students (including females) in conducting the proposed research. Overall, the PI will establish an integrated research and educational program to train future scientists and engineers in the area of next generation wireless networks and to inspire young people's interest (including K-12 students) in science and engineering fields at the early stage of their learning career.

在过去的几十年里，我们经历了家庭和办公室蜂窝电话和 Wi-Fi 网络的使用以及面向不同应用的新兴无线技术的巨大增长。用于接入无线网络的轻型手持设备的大量增长导致对无线服务的需求呈指数级增长，并导致无线频谱严重短缺。为了克服这些问题，除了与授权用户共享频谱之外，还需要一种新的无线架构来增强网络覆盖范围、容量和安全性。该 CAREER 项目的研究目标是显着推进无线通信领域的发展，期望通过 a) 设计一种新颖的通用无线虚拟化架构 (Wi-Vi) 来为使用无线电的用户提供无线服务，从而开辟变革性的研究方向。 -即服务，Wi-Vi架构将增强网络容量、覆盖范围、无缝移动性和能源效率，从而能够支持下一代无线系统中的数万亿台设备； b) 扩展所提议的 Wi-Vi 框架的范围，以实现性能隔离、安全和隐私，同时为不同无线环境中的用户提供服务质量/体验。此外，这项工作将帮助许多领域的研究人员了解无线通信如何影响智能电网、电子医疗、车辆网络、下一代蜂窝网络、物联网、网络物理系统和安全网络空间等新兴领域。 PI 将培训下一代无线网络领域的下一代科学家和工程师，指导本科生和研究生级别的研究人员（包括少数族裔和女性），并激励 K-12 学生在科学和工程领域进行研究。通过实践演示，他们学习生涯的早期阶段。该职业项目重点关注无线虚拟化 (Wi-Vi) 框架的设计、分析和评估，通过结合不同的无线资源和基础设施，超越与许可用户的频谱共享，将其用作网络上的点播服务，增强网络容量、覆盖范围、能源效率和安全性的目标。 PI 将使用系统方法开发 Wi-Vi 架构，以提高整体网络性能。具体来说，本研究的意义包括：1）开发通用无线虚拟化框架，通过扩展或缩小虚拟无线运营商的无线资源来满足无线用户的动态需求； 2) 研究和实施覆盖和容量驱动的移动虚拟网络运营商（MVNO）之间的最佳无线资源共享； 3）开发基站级、MVNO级和用户级优化以及服务质量（QoS）配置的系统方法； 4）通过动态网络分段，无线虚拟化在网络安全中的应用； 5) 通过在 NSF 资助的云测试平台（例如 ROAR、Chameleon 等）中进行广泛的模拟和实验来验证和评估所提出的新技术。随着无线网络触及我们社会的各个方面，职业奖将产生广泛的社会影响，以及将支持增强我们的国家无线能力和网络安全。该项目将影响无线通信应用的许多新兴领域，例如智能电网、电子医疗、车辆网络、下一代蜂窝网络、物联网、网络物理系统和安全网络空间。 PI 将通过无线虚拟化和下一代无线网络的新课程和模块向学生传播知识，从而培训本科生和研究生。将重点努力吸引代表性不足的学生（包括女性）参与拟议的研究。总体而言，PI将建立一个综合研究和教育计划，以培训下一代无线网络领域的未来科学家和工程师，并激发年轻人（包括K-12学生）在其早期阶段对科学和工程领域的兴趣。学习生涯。
