Here is a possible solution to this:

Instead of measuring the distance using time, let's measure it
in terms of packet counts.  So every time we receive a fragmented
packet, we find all waiting fragments with the same src/dst pair.
If the id is identical we perform reassembly, if it isn't we increase
a counter in that fragment.  If the counter exceeds a threshold,
we drop the fragment.

Cheers,
