1.8 NETWORKS

GeoNet uses network technology that is self-configuring and self-healing. If all
nodes are in range of the supervisor, then data from the nodes is sent directly
from the nodes to the supervisor (a star topology).
If direct communication is not possible for some nodes, then other nodes will
automatically relay their data to the supervisor. This effectively creates a cluster
tree topology. The figure below illustrates this concept.

FIGURE 8: Cluster Tree Network Topology

Each transmission from node to supervisor or node to node is considered one
"hop". Examples of hops are shown in figures above and below. Up to four hops
can be made between a node and the supervisor. With the ability to hop comes
the ability for the supervisor to communicate with nodes that have not
