Course Description:

The purpose of this seminar is to discuss some advanced concepts in wireless and mobile networks. The material in the seminar, drawn mainly from the research literature, will be presented in a bottom-up fashion. Challenges and an introduction to main issues are presented first, to form the foundation for further discussion. This is followed by discussions of mobility management, sensor networks, location awareness, business models, and some security issues.

Each participant will be requested to pick a topic as part of the presentation series (each for ~40 minutes, plus ~20 minutes discussions) and write an essay (12~15 pages) based on the assigned papers. The objective of the seminar is to help students build on their networking knowledge and keep them up to date with the new technologies in the ever changing and dynamic world of wireless networking and mobile communications.
