In this case, all nodes have properly meshed, and all nodes can communicate with the gateway. However,
this network could potentially strand end nodes. Figure 17 shows another possible mesh of the same
network.
Figure 17.
Network Containing Distance, Example 2
In this mesh configuration, eight end nodes in range of both R
1
and R
2
join with R
1
. This leaves one end
node stranded from the network. This can be corrected in the following two ways:
1.
Move the set of 8 end nodes to where they can only communicate with R
2
. This prevents them from
possibly joining R
1
.
2.
Add an additional router that is in range of the single end node. This introduces the possibility of
creating additional hops in the network, but also guarantees coverage of all end nodes.
