Algorithm 2 Calculate fingerprint for a set of RSSI values of a beacon

1:procedure getFingerprint(Int $region\_id$, Int $beacon\_id$, DataFrame $RSSI$) 2:      fingerprint[‘mean’] = RSSI[‘RSSI’].mean() 3:      fingerprint[‘timestamp’] = RSSI[‘timestamp’].mean()      ▹ Average the timestamps 4:      if $region\_id==beacon\_id$ then 5:            fingerprint[‘weight’] = 0.75 6:      else 7:            fingerprint[‘weight’] = 1.0 8:      return $fingerprint$
