History

The Complex Networks and Security Research (CNSR) Lab at Virginia Tech was founded in 2011 by Professors Tom Hou and Wenjing Lou. It is a merger of the former Complex Network Systems Lab in the ECE department and the former Cyber Security Lab in the CS department.

Mission

The mission of the new CNSR@VT lab is to conduct basic and applied research in a broad range of topics in networking, wireless, and cyber security. We explore novel concepts and ideas related to protocols and systems of the future pervasive cyber infrastructure, and design scalable architecture and trustworthy protocols for next-generation networks.

Current Research Interests

There are two main research thrusts at CNSR@VT:

Wireless Networks Research

  • Mathematical Modeling and Theoretical Foundation: Interference cancellation modeling and analysis, MIMO ad hoc networks, cognitive radio ad hoc networks, wireless energy transfer
  • Network Optimization: Large-scale, discrete and continuous non-convex optimization problems that arise from cross-layer optimizations involving advanced physical layer technologies
  • Algorithm and Protocol Design: Provably optimal and near-optimal algorithms, distributed algorithms and light weight protocols for wireless networks (e.g., ad hoc and sensor networks, multi-hop cooperative communications, opportunistic routing, network coding)

Cyber Security Research

  • Wireless Security: security and privacy in wireless networks and mobile computing, confidentiality and authentication, anonymization and information privacy, cognitive radio networks security, cross-layer methods for security enhancement, location privacy
  • Information Security in Cloud Computing: outsourced data privacy, auditing, search over encrypted data, computation outsourcing privacy
  • Security and Privacy in Cyber-physical Systems: e-healthcare systems and smart grid

News

  • June 2014: Dr. Lou has been promoted to Full Professor (VT announcement).
  • May 2014: Prof. Lou is named the 2014 Virginia Tech College of Engineering Faculty Fellow, in recognition of her extraordinary performance in research (photo, CoE news release, and CS news).
  • April 2014: Prof. Tom Hou's new book Applied Optimization Methods for Wireless Networks has been published by Cambridge University Press.
    This book is written in a unique style. It is a valuable resource for faculty, graduate students, and researchers in the communications and networking area whose work interfaces with optimization. It teaches you how various optimization methods can be applied to solve complex problems in wireless networks.
  • April 2014: Prof. Lou delivered a keynote address titled "Toward Privacy-Assured Searchable Cloud Data Services", at International Workshop on Security and Privacy in Big Data (BigSecurity 2014), collocated with IEEE INFOCOM 2014, in Toronto, Canada.
  • Dec 2013: Dr. Lou has accepted an invitation to serve on the editorial board of Journal of Computer Security (JCS). JCS is a top journal in the area of computer security that presents research and development results of lasting significance in the theory, design, implementation, analysis, and application of secure computer systems.
  • Nov. 2013: Prof. Tom Hou has been named an IEEE Fellow for contributions to modeling and optimization of wireless networks. The status of Fellow is one of the most prestigious honors of the institute, bestowed upon less than one-tenth of one percent of the annual voting membership of IEEE. See Virginia Tech College of Engineering news release.
