Seminar Description and Prerequisites

Mobile and wireless networks have been undergoing rapid growth in the past several years. This seminar covers topics ranging from physical layer to application layer in the wireless and mobile networking fields. In this seminar, we will explore the physical layer issues of the wireless communications, wireless cellular telephony, ad-hoc networks, mobile IP and multicast, wireless LAN (IEEE 802.11), security, Bluetooth and WAP, etc. The purpose of this seminar course is that by reading the selected paper and book chapters, people gain general knowledge about wireless communication technologies, as well as the ongoing research activities.

The course prerequisites include a course on networking, a course on operating system, a course on algorithm, and reasonable data communication knowledge. To register for this seminar, you need to fill out a course override form and get the instructor's signature. The forms will be distributed at the first meeting, or you can get them at the main office of computer science department.
