The Networks and Communications (NC) lab at the LUMS School of Science Engineering (SSE) conducts research in Networking Systems. Specific research areas include wireless networks, congestion control, network and systems security, data provenance and forensics, routing, energy-efficient networking, data centers, traffic engineering, network architecture, and distributed multimedia systems. The lab supports both experimental as well as theoretical research in these areas. The group has a strong track record of publishing research at leading International Conferences and Journals including ACM Sensys, IEEE INFOCOM, ACM CoNext, IEEE/ACM Transactions on Networking, ACM SAC, ACM Grid, ACSAC, DCOSS, DRCN, Global Internet, ICC, and Globecom. The lab has maintained collaborations with University of California (Davis), University of Pittsburgh, University of Illinois (Chicago), Swinburne University of Technology, Freiburg University, SRI International, Cisco (San Jose), Marvell Semiconductor and Max Planck Institute for Software Systems.
