Throughput in a DigiMesh network can vary by a number of variables, including: number of hops,
encryption enabled/disabled, sleeping end devices, failures/route discoveries. Our empirical
testing showed the following throughput performance in a robust operating environment (low
interference).
Note: Data throughput measurements were made setting the serial interface rate to 115200 bps,
and measuring the time to send 100,000 bytes from source to destination. During the test, no
route discoveries or failures occurred.
When a node receives an API TX Request (API configured modules) or an RO timeout occurs
(modules configured for Transparent Mode) the time required to route the data to its destination
depends on a number of configured parameters, whether the transmission is a unicast or a
broadcast, and if the route to the destination address is known. Timeouts or timing information is
provided for the following transmission types:
Note: The timeouts in this section are theoretical timeouts and not precisely accurate. The
application should pad the calculated maximum timeouts by a few hundred milliseconds. When
using API mode, Tx Status API packets should be the primary method of determining if a
transmission has completed.
A building block of many of the calculations presented below is the unicastOneHopTime. As its
name indicates, it represents the amount of time it takes to send a unicast transmission between
two adjacent nodes. It is largely dependent upon the mac retry setting (RR). DigiMesh networks
assume that the average number of mac level retries across a multi-hop wireless link will be 3 or
less. It is defined as follows:
A broadcast transmission must be relayed by all routers in the network. The maximum delay
would be when the sender and receiver are on the opposite ends of the network. The NH, NN, and
MT parameters define the maximum broadcast delay as follows:
