indoor localization
Indoor Localization
  • Localization: To locate a device.
  • Why not GPS?
  • Wardriving/ Warwalking: Searching for a Wi-fi network while changing location.
  • Cost and human effort associated with other indoor localization methods.
spinloc introduction
SpinLoc: Introduction
  • Hypothesis: Maximum attenuation is observed when the human is in between the device and the AP.

Signal Transmission in Indoor environment

  • EDP (Energy of Direct Path) Vs RSSS (Receiving signal strength)
edp vs orientation
EDP Vs Orientation
  • In all cases, we have least EDP at 180 degrees.
performance evaluation
Performance Evaluation
  • Angle error reduces with increasing SNR
spinloc limitations and future research
Spinloc Limitations and future research
  • Requires user to spin once.
  • Depends on availability of atleast 3 APs with high SNR.
  • Results could vary with increasing crowd.
  • Need to be able to localize based on turns instead of 360 degree rotation.
  • Should be able to constantly localize without user making full rotation.
