CS547 Wireless Networking

Course Overview

Ubiquitous access to information, anywhere, anyplace, and anytime, will characterize whole new kinds of information systems in the 21st Century. These are being enabled by rapidly emerging wireless communications systems. These systems have the potential to dramatically change society as workers become "untethered" from their information sources and communications mechanisms. This course introduces multihop wireless networks including wireless ad hoc networks, wireless sensor networks, and wireless mesh networks. It explains in detail and depth the design and optimizations of these wireless communications networks. As an advanced graduate course, this one will combine extensive reading and discussion of the research literature with in-depth research. As prerequisites, the students should have basic knowledge of both wireless communications and algorithm designs.
