What technique do individual nodes use to form a mesh network?
Forward error correction and Viterbi codes
Acting as store-and-forward digipeaters
Discovery and link establishment protocols✓Correct answer
Custom code plugs for the local trunking systems
Explanation
Mesh nodes transmit and listen for beacon or hello messages to find their neighbours, then negotiate links and exchange routing information so traffic can be relayed over several hops. This runs automatically and continuously, which is what lets the network reconfigure when a node appears or disappears.
