A quick (nontechnical) explanation of the new flood routing algorithm coming soon to Meshtastic 1.3/2.0!

In Meshtastic 1.2 (and prior), up to three devices will randomly rebroadcast a received packet to spread that packet to other devices on the network. Each time a packet is rebroadcast, we call this a "hop".

Meshtastic 1.3/2.0 changes that in two ways:

First, devices on the edge of the network are preferred to rebroadcast the packet. This will help ensure that distant devices will receive the transmitted message.

Second, we introduce the concept of a router that is weighted even higher on the network so your message will more likely pass through them rather than regular nodes.
