For years I keep harping about how currently used routing techniques are
so very b0rken. Cellular wireless by its very nature is ideal for geodetic
routing, which uses local-visibility routing tables strictly. Meaning, all
the admin traffic is purely local, among immediate, and
neighbours'-neighbour nodes. Meaning, the thing is infinitely scalable, as
bits are sufficiently cheap to be able to address the entire visible
universe at Planck scale, if you think you need to do that. Mapping the
entire solar system down to cubic micron is a piece of cake.
As a boon, if you use geographic coordinates for node addresses (obtained
from connectivity constraints or plain old GPS), you can't get address
collisions (no two nodes can occupy the same place at the same time), and
you can use switching instead of routing, if you design the packet header

High-quality links are local by nature. This doesn't translate into
latency, if you use (eventually purely photonical) cut-through switching
as described above, using store-and-forward as fallback.
