Sommersemester 2021

Wireless Sensor Networks (Drahtlose Netze)


all lectures in summer term 2021 are online!

With the term ‘wireless sensor networks’ we refer to collections of hundreds or even thousands of ‘sensor nodes’. They allow for a widespread observation of distributed natural phenomena without interfering much. A sensor node is an electronic device equipped with sensors, computing units, and wireless communication modules. This mini-computer is equipped with a battery to survive for weeks or months. It measures features of its environment, processes the data, and communicates it to a neighboring node or to a base station. There is a wide variety of applications that come with different challenges. The main challenge is minimization of energy consumption.


In this lecture we cover among other subjects:


  • hardware aspects of sensor nodes
  • physics and protocols of wireless communication
  • routing in wireless networks
  • time synchronization and localization in wireless networks
  • data management and data processing in wireless sensor networks
  • applications of wireless sensor networks
