It is shown in Figure 5 based on The formation of
IEEE802.15.4 Ad Hoc network. Nodes need to initialize the
IEEE802.15.4protocol stack and network layer[2, 3]. The
initialization is completed, and each node will set up its own
LAN ID, logical channel and short address to a prearranged
value in the network. Nodes need to communicate, and need
to establish routing information.
