Wireless Sensor Networks



  • 18.07.2016 Lecture is canceled. Please visit PhD defense of Christian Ortolf at 1pm in 101-02-016/018 instead
  • 18.04.2016 2pm, 101-01-009/013 First lecture
  • 11.04.2016 Website is online 


In this lecture we present the networking aspect of sensor and actuator networks. Starting from existing systems we present algorithms and protocols for all networking layers. We discuss the lifetime of a sensor network and energy consumption. Also, the coverage, localization and data aggregation will be covered.
