Research Areas - Communications & Networking (COMNET)
Communications and networking research covers the range from theory to implementation of on-chip, optical, wired and wireless communication networks. Algorithm and protocol design, and system-wide policy considerations in large scale deployments of communication infrastructures are all areas of active research. Fundamental work on some of the core problems of information theory, networking, data compression, coding, and multi-user communications is emphasized. Problem formulations are guided by the needs of modern applications such as magnetic recording, digital television, voice-and-video over wireless, and gaming.
