What technique do individual nodes use to form a mesh network?
The correct answer is C: Discovery and link establishment protocols. Individual nodes in a mesh network use discovery and link establishment protocols to form the mesh network. These protocols allow nodes to find each other, establish connections, and build the mesh topology.
Discovery protocols allow nodes to detect other nodes in range and learn about the network topology. Link establishment protocols set up communication links between nodes. Together, these protocols enable nodes to automatically form a mesh network without manual configuration. Nodes discover neighbors, exchange routing information, and establish links to create the mesh. This is how mesh networks self-organize and adapt as nodes join or leave the network.
Exam Tip
Mesh network formation = Discovery and link establishment protocols. Remember: Nodes use discovery and link establishment protocols to find each other and form the mesh network automatically.

Real-World Application
You power up a new mesh network node. It uses discovery protocols to scan for other nodes in range and learns about the network topology. Then it uses link establishment protocols to set up communication links with neighboring nodes. Through these protocols, your node automatically joins the mesh network without manual configuration.

Why Other Options Are Wrong
Option A: Incorrect. Forward error correction and Viterbi codes are for error correction, not for forming mesh networks. They don't help nodes discover each other or establish links.
Option B: Incorrect. Acting as store-and-forward digipeaters describes a function nodes can perform, but it's not the technique used to form the mesh. Discovery and link establishment protocols are needed first.
Option D: Incorrect. Custom code plugs are for trunked radio systems (like DMR), not for mesh network formation. Mesh networks use discovery and link establishment protocols.
