IC636: Wireless Networks (Fall 2013)
Instructor: Kyung-Joon Park Office hours: By appointment, 3-309 DGIST
Textbooks:
Course Description: Several major topics related to wireless networking will be covered, including a brief overview of physical layer issues, multiple access, TCP over wireless, and routing protocols for wireless LANs and ad hoc networks, sensor networks, and some security-related issues.
Grading policies: Exam 70%, Homework 30%
Announcement:
- Reading assignment 1: Submit a summary (including your own opinions) of the paper by Gupta and Kumar in the reading list by the midterm exam.
- Reading assignment 2: Submit a summary (including your own opinions) of the paper by G. Bianchi in the reading list by the midterm exam.
- Reading assignment 3: Summarize the key differences between the single-hop model in "On the capacity of wireless CSMA/CA multihop networks" and that in the paper by G. Bianchi (due: November 12).
- Homework: Submit your summary why two-hop relay is better than direct communication in mobile ad hoc networks (due: November 26).
- Hint: Find "interference-limited" and "distance-limited" in this paper
- Reading assignment 4: Submit a summary of the two papers on TCP in the reading list. Please note that the first one is quite long (due: December 17).
- The midterm exam is scheduled at 1:30 pm, October 24
- The final exam is scheduled at 1:30 pm, December 19
