Project Summary

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. 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.
