Algorithm 2. The Kullback-Leibler multivariate Gaussian positioning method

	- A database for each RP is set using RSS measurements from different locations.
	- The RSS measurements from the APs of smartphones from unknown locations are set in the same way as the database of the offline phase with respect to the similar media access control (MAC) address.
	- The minimum symmetric Bregman divergence is estimated using Eq. 27.
	- The previous step is repeated for different APs until the minimum distance is obtained.
