I worked on a similar project for Motorola and it had limited commercial success.

Very dense topologies need to aggressively handle broadcast storms such as ARP storms. Very fragmented topologies need to handle delay tolerant networking.

In any event, search for "Mobile Ad-hoc Networks" will show work that has been done previously.

thanks! yes, we are very delay tolerant and a typical text message (or flooded location update) takes a few seconds to get across our likely max # of hops (which is only three, due to our uhttps://github.com/meshtastic/Meshtastic-esp32/blob/master/d...)

We initially used the RadioHead mesh router (which seems to be a variant of DSR), but we are switching to something else soon. Misc notes here: https://github.com/meshtastic/Meshtastic-esp32/blob/master/d...
