Research

Researchers in the Communications and Networking Laboratory are actively engaged in addressing key challenges that face the future generation broadband communication networks.

More specifically, researchers in the wireless communications and networking area are investigating design and fundamental information-theoretic analysis of energy efficient next generation wireless networks that can deliver very high data rates anytime anywhere, via the MIMO-OFDM technology proposed for the new wireless communication standards such as Long-Term Evolution — Advanced (LTE-A), and re-thinking of cellular network design via a hierarchical structure involving macro, micro, pico and femto-cells. Emerging technologies such as cognitive radios are also being investigated to address the problem of spectrum scarcity. A number of researchers are also investigating how to design more energy efficient wireless video communication networks.

Researchers in the optical communications domain are investigating the problem of reducing the carbon footprint of the next generation Internet (for more information, see Centre for Energy-Efficient Telecommunications), along with the design and analysis of broadband networks that seamlessly integrate wireless and optical communications technologies via Passive optical networking (PON). Networking researchers are investigating practical inference methods for Internet measurement, sophisticated accurate clock synchronization techniques over the Internet and aspects of Information-theoretic security.
