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.
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, cognitive radio networks security, cross-layer methods for security enhancement, location privacy
- Security and Privacy in Cloud Computing: outsourced data privacy, search over encrypted data, computation outsourcing privacy
- Security and Privacy in Cyber-physical Systems: e-healthcare systems and smart grid
- October 2013: IEEE CNS 2013 will take place Oct 14-16 in Washington DC area. Check out this conference at IEEE CNS website and a brief introduction at IEEE ComSoc Blog.
- July 2013: Our research paper "Bicriteria optimization in multi-hop wireless networks: Characterizing the throughput-energy envelope" has been selected as the Spotlight Paper for the September 2013 issue of the IEEE Transactions on Mobile Computing! The paper will be highlighted on the journal home page and will be available to the public for free for 30 days.
