3.2.3. Constructing the Network

Remote devices may join once a core network has been established. New devices (children) can connect to

existing devices (parents) through either association or direct connection.

3.2.3.1. Joining Through Association

In association, the child proactively discovers the network. Once discovered, the child requests a connection as

shown in Figure 3.
