Complex Networks and Security Research (CNSR)
| URL: http://www.cnsr.ictas.vt.edu Contact: Wenjing Lou The Complex Networks and Security Research (CNSR) Laboratory at Virginia Tech was founded in 2011 by Profs. Tom Hou and Wenjing Lou. It was merged from 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 the next generation networks.
