Depedent node is a node that does not run Staex, but is a part of Staex network. Such a node has its own address in Staex network, but otherwise depend on its parent node that runs Staex. The parent does routing, encryption and everything else on its behalf, i.e. using their public and private keys.
It is impossible to encrypt the traffic between the parent and its dependent, hence we allow only nodes in the same local network to be dependents.
A depedent node can only send traffic to Staex network in response to the traffic that came from this network.
Microcontroller-based devices that speak IPv4 are good candidates for depedent nodes: IP cameras, network printers and scanners, smart meters, smart lighbulbs etc.
