6 Latency

Figure 6-1 gives an overview of the average one router node ping latency with error bars, denoting the maximum and minimum latency values recorded during the test. The setup for this test has the BR sending 3600 packets to the RN with a size of 64 bytes; the time for each packet is recorded and the average is plotted.

The test results show that the change in network configuration does not affect the one node latency by a high margin. The histograms for the latency tests of each network configuration can be found in Section 8.

Figure 6-2 shows the change in latency, measured in milliseconds, in a maximize responsiveness network configuration using different PHYs.

Note: Increasing the PHY data rate results in a decrease in latency.

Figure 6-3 shows the change in ping time, measured in milliseconds, as the number of intermediate hops is increased by connecting more router nodes.

A given ping packet is delayed by one of the intermediate hops when the hops have to send another control packet to forward this data packet. While the probability of this increases with higher control overhead, this is still expected to happen only for a small portion of the network. This is corroborated by the results seen in Figure 6-3.
