How to combine several Arduinos into a distributed wireless network?

Question

Arduino

There are a dozen Arduino Nanos, a few Arduino Unos.
To combine them, there are modules on NRF24L01 (frequency 2.4 GHz) and modules operating at a frequency of 433 MHz (one board is a receiver, the second is a transmitter).
To connect to the local network, there is a wi-fi module ESP8266 and ethernet ENC28J60.
From the side of the local network, a server with Windows will work.
Question: how to connect all Arduinos into a distributed network so that arbitrary data can be transmitted over it, so that the network itself is rebuilt when adding and removing nodes, and has two points of connection to the local network (to increase fault tolerance and load distribution)? Is there a ready protocol or library for this? Or do you have to invent everything yourself? Or is this completely impossible?

Answer 1

In principle, this is possible, there are no ready-made libraries, that's for sure, but the question remains, why?
