It's called thread drift.

If you're doing a relativistic pingpong to direct line of sight nodes
then the proof is very easy: you cannot exceed the speed of light.
If someone claims to be closer to you than c allows for, he's
probably lying.

If you use GPS or other location services, and talking to further
nodes then liars are also easily detected, though long-range grid deformations
are more difficult to detect (but also a far more expensive illusion
to maintain).

The proper way to deal with liars is to refuse routing their packets.
