Hacker Detection: Jamming in a Wireless Sensor Network


Wireless Sensor Networks (WSN) can be deployed for monitoring secure areas. Each sensor (or “mote”) communicates with nearby motes. A jammer attempts to interrupt this communication by flooding the motes with information, preventing meaningful communication between the motes.

The RET Program

The Research Experience for Teachers is a two-year experience for High School Science, Math and Technology teachers, funded by a grant from the National Science Foundation.



  • Research areas include:
  • Identifying neighbors.
  • Jamming detection.
  • Reporting jamming.
  • Determining the jammed areas.
  • Mapping the jammed areas.
  • Performance analysis.
  • Students will:
  • Calculate wavelength of EM waves.
  • Simulate a wireless network of cell phones (thought experiment).
  • Develop a method for identifying jamming and location of jammer.
  • Use laser pointers and diffraction gratings to demonstrate EM interference

Simulation Results

  • Calculations and Analysis are extrapolated through a program for different sized hypothetical networks.



Students are asked to write a short essay on the ethical and practical effects of jamming technology such as cell phones. Students also perform a traditional lab on electromagnetic interference patterns with laser pointers and diffraction gratings.

  • Students:
  • Calculate the wavelength of 2.4GHz EM radiation (used in motes and cellphones).
  • Simulate a network where they are the motes and text messages are the means of communication.
  • Describe how they would detect a jammer, and locate that jammer.
