• NuPIC Wifi Localization based on signal strength and link quality

• NuPIC does best in samples that vary in time and can generalize from slight changes

• Prediction of signal strength based on time steps (NuPIC platform)

• Inputs to Prediction: Signal Strength, Link Quality

• Help Menu (python wifi.py -h)

  • --version show program's version number and exit
  • -h, --help show this help message and exit
  • -u, --uncached uncached scan
  • -d <DEVICE_NAME>, --device=<DEVICE_NAME> wireless device,default=wlan0
  • -r , --rescan= rescan period (sec), default=2
  • -e , --emulate= fluctuation emulation RSSI, default=-5
  • -a , --age= aging RSSI threshold, default=-70
  • -f <ESSID_NAME>, --filter=<ESSID_NAME> filter ESSID string
  • -t <TIME_STEP>, --timestep=<TIME_STEP> set unit time step, default=5

  Example usage: python wifi.py -u -dwlan0 -r2 -a-80 -fDIRECT -t5

• Zones based on RSSI to determine proximity

  • Zone A (+36, -30)
  • Zone B (-30, -40)
  • Zone C (-40, -50)
  • Zone D (-50, -60)
  • Zone E (-60, -70)
  • Zone F (-70, -80)
  • Zone G (-80, -90)
  • Zone H (-90, x)

• output

  • wlan.csv
  • graph (matplotlib requirement)
  • Compare raw rssi, predicted rssi based on samples in time

• Note:

  • due to memory constraints, it is best to use filter to perform wifi model localization of
  • uncached options requires root access for full scan

• ESSID Station is best with WIFI-DIRECT for Testing (DIRECT-*) and move to fluctuate signal
