Let's say on my small property I set up a mesh wireless network of three nodes. It's just a tiny bit bigger than two-node WDS.
Now let's say two neighbors set up one wireless node each, and another neighbor sets up two nodes.
How do I best combine these networks? None of the mesh protocols I've seen (BATMAN, 802.11whatever) handle peering multiple mesh networks. Each will want to prioritize its own traffic to its own egress point (or at least I would for mine).
If one of our egress points goes down, are there any current routing systems for sending packets out through other neighboring mesh networks?
I see this as critical. My example is trivially small. A "mesh" of tiny neighbors can cheat. A 200MHz ARM CPU with 128MiB can handle at most 100 nodes nearly with brute force. But now consider a mesh of these meshes. A neighborhood group can set up one mesh, and a neighboring group can set up another. Each has hundreds of nodes and tens of egress routes at a minimum. I haven't seen any widely supported protocols for this situation, and this is the one I think could help.
