Wireless Networking aka “Wireless for IoT Class” (OLD HOMEPAGE! It was taught in 2023!!)

Course code: CS4222/CS5422

Instructor: Professor Ambuj Varshney

Contact: ambujv@nus.edu.sg, COM3: #02-25

Office Hours: Friday, 4 - 6 pm (By appointment, please send email)

OVERVIEW

This course offers a introduction to the field of wireless networking and the rapidly expanding world of the Internet of Things (IoT). It covers various layers of wireless networking, including physical, link, MAC, routing, and application, and discusses relevant wireless standards such as WiFi, Bluetooth, ZigBee, cellular networks for IoT (NB-IOT), and long-range standards such as LoRa. In addition, the course explores emerging technologies like LiFi (visible light communication) and backscatter. The course also focuses on the energy efficiency of IoT devices and the integration of sensing, communication, and processing. Throughout the course, students will have the opportunity to apply these concepts through hands-on projects that involve creating software prototypes on real IoT devices.

PROJECTS

We will use the following platform for conducting projects in the course:

We also have limited quantities of following platform for ambitious group of students:

Texas Instruments CC1350: Multi Protocol Development Kit (Available for 20 groups of students)

ASSESMENT

Here are important information regarding the final assesment:

Final assesment is hard-copy, paper-pen
Duration: 2 hours
Assesment is open-book. You are allowed to bring lecture notes, books, and any other non-electronic resources
Laptops are NOT allowed in the assesment hall. However, you are allowed to bring approved calculator.
There are Five Questions, with overall allocated marks being 40

USEFUL RESOURCES

Interviews and Keynotes

The following link contains relevant videos for the course: Video list

COMMUNICATION

The course has its own dedicated Slack page, which serves as a platform for communication among the instructor, teaching assistants, and students. Additionally, students are encouraged to share news and articles pertaining to the topics of IoT and wireless within the Slack workspace.

GRADING

The assessment of this course will be conducted as follows:

Continuous assesment/assignment (70% of the grades)
Final assesment, open book (30% of the grades)

The detailed breakdown of various components is as follows:

Component	Weightage (in percentage)
Assignment 1	3%
Assignment 2	12%
Assignment 3	13%
Tutorials	5%
Project	32%
Bonus	5%
Final assesment	30%

NOTE: We had to deviate from original allocation of marks, as we had cancelled Assignment 4

Policy regarding bonus mark allotment: There are multiple ways for you to get bonus marks:

There are students who may go well beyond the scope of the project in their implementation, experimentation, presentation and execution of the project. Teaching assistants would identify such groups of students (from project submission and report), and we would consider them for bonus mark allocation.
We have experimented with the use of ChatGPT in some lectures of the course. If you could suggest some non-conventional (other than simple Q&A) ways of using ChatGPT that have helped you learn wireless communication in the course, please send them to ambujv@nus.edu.sg with the subject line: CS4222 ChatGPT. We may consider them for bonus marks depending on their novelty, creativity, and uniqueness of the prompt or use case. Please send it before 28th of April 2023. Grading in this case would be subjective at the discretion of the professor.

READINGS

The course does not have a textbook. Nonetheless, we recommend the following books for learning about wireless communication and networking and Internet of Things (IoT).

POLICY REGARDING USING AI TOOLS

We are experiencing a major shift in the computing landscape with the emergence of advanced tools such as Language Language Models (LLMs) such as OpenAI ChatGPT. These tools are poised to have a significant impact on the field, and we are embracing this change by incorporating them into our course curriculum. The CS4222/5222 course will be one of the first (if not the first) course in the world at a major univeristy to actively use OpenAI’s ChatGPT in teaching wireless technology. Students will be provided with “prompts” to work with the model and we may also propose projects for more ambitious students to utilize ChatGPT. However, we will not be using ChatGPT for tutorials in this iteration of the course. It is important for students who utilize ChatGPT to clearly indicate that they have employed the tool.

IMPORTANT: It is important to note that Large Language Models (LLMs) are still in the early stages of development and may not always produce accurate results. Therefore, these tools should only be used as a supplement, not as the primary source of information, and one should use them with caution.
