We need to decide of a topology. Opennet has an interesting concept, where public IPs are hidden behind VPN gateways:


This has a few advantages:

  1. strong over-the-air encryption
  2. no need to change gateway if network topology changes
  3. access to the internet only to subscribers

We are also considering ad-hoc mode and OLSR, see network topology.

Some more tests are required but so far i am thinking of:

We also need to figure out how nodes are interconnected, at the physical level. Do we want a tree?

Update: we should consider this mostly done - we are using ad-hoc mode with BATMAN or ?babeld on top. the vpn gateways todo remains for the VPN part, but we are still thinking of using vpns to connect disconnected segments. --anarcat
