An Efficient Normalized Rank Based SVM for Room Level Indoor WiFi Localization with Diverse Devices

Algorithm 1

Proposed normalized rank transformation method during runtime phase.

(I) Dimensionality check

    for do

     for do

      if

       Keep of Ob vector at the position ()

      elseif   &  

       Pad position () with zero value

    Loop

(II) Normalized rank transformation

  (i) Keep only non-zero positions and get the new vector

  (ii) Rearrange RSSI value in ascending order.

  (iii) Assign transformed Normalized Rank value:

      Initialize the Normalized Rank (NR-Ob) vector

      for do

        if

        else

      Loop

      Normalize NR-Ob vector by and remapping to dimensional space

     Consider the transformed normalized rank vector for positioning

(III) ML Classification

(IV) Return the final position
