7.1 Preferred Parent

The preferred parent test case shows the required time for a router node to switch to a different parent router node to improve connection. In this example, an unconstrained 3-hop network is presented with a new router node, and the time for switchover is measured. The connection is shown in Figure 7-1.

Router Node 4 is introduced into the network, allowing adjacent router nodes to use as an alternative route to the border router (see Figure 7-2).

Preferred Parent Example: Connect RN4 Figure 7-2 Preferred Parent Example: Connect RN4

Figure 7-3 shows Router Node 3 switching connections from Router Node 2 to Router Node 4, decreasing the number of hops required to communicate with the BR.
