  1. Programming Assignment #3Proximity-Based Localization

  2. Goal • To estimate a mobile user’s position at 50 steps from the given information (get_becons)

  3. Connectivity Metric Based Solution • Connectivity Metric, CM • Cacluate the centroid of the reference points with CM >= CMthreshold • Error rate • Problem • Threshold needs to be adjusted in different environments

  4. Error rates with different threshold • Why error rate decreases? • When there is no beacon greater than threshold • Use the previous position • Calculate the current position based on the velocity of mobility

  5. Avg / Weighted Avg of Received Beacons Calculate the centroid of beacons Calculate the weighted average of beacons Harmonic mean/Weighted harmonic mean

  6. Use the best beacon Calculate the centroid of one (or more) best beacon
