Answer could be

As,
the sum of all the numbers of small squares should equate to sum of numbers formed by the bigger suqares (from Right bottom to Top left)
That is for example:
? = ? (square of size 1 X 1) 0 + 1 + 4 + 7 + 6 = 3 + 5 + 8 + ? (of size 2 X 2) - thereby giving ?=2 and similarly for size 4 X 4.
