paf-kiet - Fall 2018
We are observing the emergence of many new exciting applications (e.g., autonomous driving, virtual and augmented reality applications, smart city, and remote healthcare). One of the key enabling communication networks for these applications are going to be cellular networks. However, cellular networks are facing many scaling and security challenges due to explosive growth along multiple dimensions:
• Ten-fold increase in traffic volume over the last few years,
• Rapidly growing number of diverse devices (e.g., 3 billion diverse Internet of Thing (IoT) devices are expected to be connected to cellular networks by 2019)
• Demanding applications (e.g., virtual reality, driver-less cars, and remote surgery)
Addressing these challenges will require a fundamental rethinking of the cellular architecture and raises the following key questions:
• What are the key performance and security challenges introduced by the rapid growth in cellular traffic and the emergence of new applications?
• What are the fundamental design issues with existing cellular architectures (e.g., 4G/LTE) in meeting the performance and security requirements of future applications?
• How can we design future cellular networks (e.g., 5G) that are scalable and secure? What will be the key technology enablers for 5G and beyond?
• What are the unique challenges in improving cellular access in developing regions like Pakistan?
In this course, we will attempt to answer these questions.
This is a graduate-level course on cellular networks research. It involves lectures, paper readings, discussions, and a semester-long research project. The course will be broadly divided into three modules:
• 5G applications and performance requirements
• New technologies: SDN, NFV, and network slicing
• Research challenges: Scalability, security, and cellular access in developing regions
We will read research papers, understand initiatives by cellular operators and go over state of the art work. Students will be required to write paper summaries and participate in class discussions. In addition, students will be expected to make presentations on assigned papers and participate in a semester-long research project. Hopefully, through this course, students will generate publishable results from their research project or find some interesting topics for their long-term research.
