24. Questions to Answer Understand critical demands in 5G
Driven by 5G apps
Drives to 5G technology evolution
On extremely low latency, scalability, efficiency, reliability, security …
In 5G app contexts
First, we will start with new apps and new demands in a well-connected 5G world. We will examine what challenges and opportunities arise on VR/AR, massive IoT, smart city, autonomous driving, tactile internet, remote healthcare, to name a few. We will cover several critical demands like extremely low latency, reliability, and efficiency/scalability.
Second, we then learn the state-of-the-art of the mainstream architecture, protocols and technologies (adopted by the giant players and standardization). We are going to cover advanced topics on NFV, SDN, edge computing, cloudlet, network slicing, RAN innovation and heterogeneous wireless technologies, etc. 
Finally, we will explore the topics of our interests and gain experience by carrying out original research projects. These topics will cover, not limited to the formal methods to understand and verify networking system design and practice; the data-driven approach to analyze and diagnose networking system behaviors, provable correct re-design which improves network performance and reliability, and many other innovations toward better application experience in 5G and B5G. 
Throughout this course, students will learn key principles in mobile 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.
