Trace Route

Because the modules use the AODV protocol which is a routing protocol capable of
finding its own path through the network it can be difficult to determine the selected
communications path.
"Trace Route" allows the communications path to be traced through the network and
determining how many hops the path is taking to get to the destination.
Figure 55 – Trace Route
The example above shows the response time from the Host to the first IP address
(192.168.0.102) is 874msec, the second IP address (192.168.0.106) is 685msec and
the third IP address (192.168.0.106) is 1373msec.
Each hop is a separate trace route discovery message from the Host device to each
remote IP address and therefore the response times can vary as they are dependent on
network lag times, throughput, interference, etc.
Each Trace Route message is broken down as follows.
1 192.168.2.108 (192.168.2.108) 874 ms
"1" = Hop number
"192.168.2.108" = DNS Name of the device.
"(192.168.2.108)" = IP Address of the device.
"874 ms" = A roundtrip response time (ping) in milliseconds from the Host IP to each
hop point.
