Figure 1: ZigBee Network Topologies
PARENT/CHILD RELATIONSHIP
ZigBee uses a parent/child relationship between network devices. The network begins with the Coordinator as the
first device on the network. When a new device (Router or End Device) associates with the Coordinator, it becomes a
child of the Coordinator and similarly, the Coordinator becomes a parent of that device. If a second device joins the
network, the Coordinator will once again become the parent and the device will become a child of the Coordinator. If
a device is not in range of the Coordinator, it subsequently joins the network through a Router, and becomes a child of
that Router. Network devices can have multiple children, but only one parent. By design, End Devices cannot be
parents and are always
children of the Coordinator or a Router.
