Sensors, getting smaller down to nano-scales, serve grandiose objectives such as Artificial Intelligence aiding and supporting humanity in the current facilitating background of Industry 4.0 and Internet of Things. This course will focus on the communication of sensors of differing scales; from nano sensors to smart dust to seismic sensors, in different media such as underground, under water, and air. Rather than device level electronics and physical layer communications, we will study networking algorithms and efficiency. This course is project-based.
