Class Overview

Mobile computing and wireless networking has become an essential part of our daily lives, with the number of mobile users and devices growing every day (there are 1 billion more mobile connections than people in this world!). New mobile context-aware applications and services emerge that utilize various sensors embedded on smart devices and Internet-of-Things. Example services include activity recognition, sign language recognition, healthcare, user authentication, obstacle detection, and even emotion recognition. We are witnessing the popularity and importance of mobile computing and networking in the industry, start-ups, as well as academic research community. In this advanced, research oriented course, we study the various research aspects that enable mobile computing; network architectures, protocols/algorithms, systems, services, applications, security, privacy, and even machine learning. Students will design class projects that develop interesting mobile applications or IoT services.

The course will consist of the following:
• Lectures by the professor on fundamentals of wireless networking and mobile computing
• Tutorials by the TA on Android programming and Arduino programming
• Presentations and discussions by the students on seminal and cutting edge research papers
• Presentations by the students on their projects
• Invited talks by KAIST graduate students who published at top mobility conferences
• A case study of MIT roofnet project that turned into successful entrepreneurship (e.g., it became Meraki that was acquired by Cisco for $1.2Billion).

The following topics will be covered:
• Mobile computing & sensing
• Wireless connectivity: LTE, Wi-Fi, ZigBee, Bluetooth, RFID, visible lights, inaudible sound, etc.
• Mobile network architectures
• Localization
• Energy efficiency
• Cloud for mobile computing
• Smartphones and novel sensing applications
• AI & machine learning for mobile computing
• Wearable computing & applications
• Connected cars, bots, voice assistants
• Mobile security & privacy
• Mobile HCI

Prerequisite

Basic understanding of networking (CS341 or equivalent) will help but not required. Programming experience at the level of upper class CS undergraduate.

Textbook

There is no required textbook, as this field changes in a very fast pace. We will instead read seminal papers and recent papers that advance the state of the art.

Grading Policy

Exams	20%	A number of quizzes throughout the semester. No midterm or finals.
Homework	30%	Programming assignments (smartphone & IoT) and paper essays.
Term Project	20%	The project must involve implementation (e.g., Android app) of your own idea. Each team should consist of 2-3 students. The project will be evaluated on novelty (is it a new idea? Or does it improve existing solutions?), usefulness (does it solve an important problem? Would people use it?), and teamwork (who did what and collaboration dynamics).
Presentations	20%	Each individual will make multiple presentations; will read and present 2-3 papers to lead the discussion. In addition, each will present as part of a project team with their elevator pitch and a demo of the project.
Participation	10%	This course will be successful only if it's interactive. Students are highly encouraged to ask questions, present their opinion, disagree, and lead discussions.

Announcements

• 9/11 Submit your biddings on paper preference for presentations & essays until 9/18 to our class email!
• 9/10 Announcements about the team formation:
  1) We will have 12 teams for this semester. There will be 10 teams with 2 people, and 2 teams with 3 people.
  2) Submit this form (http://bit.ly/cs442-team-formation-now) for team formation!
  3) You can check the current team formation status here (will be frequently updated)
  4) Since there will be only 2 slots available for teams of 3 people, we will accept the teams on first-come, first-served basis.
  5) For those of you who haven't find teammates yet, we will have a short team matching session after the class. Please stay in the classroom after class if you wish to attend the team matching session.
