CMSC 715: Fall 2024
Description: The objective of this course is to introduce the spectrum of research on the Internet of Things (IoT). The lectures cover a range of techniques in sensing, computing, communication, and wireless networking and connect them to various applications in analytics, localization, cyber-physical systems, mobile health, security, and wearables. This course is designed with multidisciplinary students in mind. Every topic begins from first principles and gradually ramps up to the system design and application, helping students to understand the state-of-the-art developments in this area and initiate research. Topics:
