Configuring Your NI WSN System
As discussed in the
Mesh Networking
section, creating a reliable and efficient wireless sensor network
requires an understanding of the physical environment the network will reside in, as well as an
understanding of the expected meshing configuration. Additionally, the following consideration needs
to be taken into account: parent devices (routers and gateways) can only have a maximum of eight end
nodes connected to them at a given time.
This introduces the stranded node problem. The stranded node problem exists when a node configured
as an end node has the possibility of not being able to join a device node. Figure 16 shows a network
consisting of one gateway, two routers, and nine end nodes.
