Sample Course Project

The team (Yuhui Feng, Ganga Reddy Tankasala, Jia Guo, Wei Tang) has built a very cool project called,HackCellular, in 2015 Fall. This project replays the identified security issues from our prior work on their own phones. It will allow everyone to do it yourself. The below is the demo made by this team. More details can be found at here.

Course Description

This course is a networking seminar, covering a broad range of hot topics in mobile networking. In particular, we focus on three major themes: (1) operational cellular networks (mainly 4G LTE networks), (2) next generation mobile networks (4G beyond and 5G), and (3) cutting-edge techniques to boost networking performance, energy efficiency, real-time operations,user experience, OTT applications, to name a few. Students will learn key principles in networking research, understand the state-of-art and recent trends, master a suite of research skills (e.g., paper reading, critique, critical thinking, problem solving, report writing, team work, communication, and presentation), and gain experience of carry out original research through course projects. Hopefully, through this course, students will generate publishable results from course projects or find some interesting topics for your long-term research.

Prerequisites

As a research seminar, we assume that students already have a solid understanding on networking fundamentals (eg., TCP/IP, WiFi networks). The students must take undergraduate/graduate networking class CSE3461/5461 or equivalent courses before. Course project is an important part of this class. Good programming skills and project experience is a must (not a plus).

Textbook and Course Materials

No textbooks are required.

This course is based on research papers from top-tiers conferences, such as Sigcomm, Mobicom, Mobisys, NSDI. Recommended papers can be offered in class. Students are encouraged to pick other high-quality papers from top venues, relevant to your research topics and interests.

Grading Policy

  • Project: 50% (team of 2-3 members)
  • Paper presentation: 25% (each: 1-2 papers)
  • In-class participation: 25% (including critique: 10% and discussion leads)
