The intent of the Wireless Sensor Networks (WSN) Knowledge Unit is to provide students with a basic understanding of wireless sensor networks and the security issues associated with them.


After completing the KU, students will be able to:

  1. Diagram and deploy a wireless sensor network.
  2. Describe the challenges associated with wireless sensor networks, including coordination, energy efficiency, and self organization.
  3. Propose and analyze appropriate security measures for wireless sensor networks.
