Pervasive Radio Mapping of Industrial Environments Using a Virtual Reality Approach

Algorithm 3

if (1 > (grid[i][j]  +  grid[i  +  1][j]  +  grid[i][j  +  1]  +  grid[i  +  1][j  +  1])

{

    grid_fav[i][j]  =  0;

    grid_fav[i  +  1][j]  =  0;

    grid_fav[i][j  +  1]  =  0;

    grid_fav[i  +  1][j  +  1]  =  0;

}

   Therefore:

    for  (i = 0;  i < ROWS; i++)

    {

        for  (j = 0;  j < COLUMNS; j++)

       {

          if ((grid_fav[i][j] == 0) && (real[i][j] == 0))

            success_grid_fav[i][j]  =  1;
