FWIW I have some background in this area and got curious how Meshtastic works so I read some of the docs and code. It seems like they are unaware of existing work even 20+ years ago, a specific suggestion is to study the state of single radio CSMA meshes in say 2005 and make a list of subjects to read on, then do that. There's a lot of stuff that happened later but in the early 2000s many people tried to make meshes out of 802.11b IBSS and a lot got written about those efforts.
