3.1.3. Joining an End Device
When an end device first comes up, it must also locate and join a PAN. End devices follow the
same process as a router to join a PAN. Once the end device has successfully joined a PAN, it can
communicate with other devices on the PAN. However, since end devices cannot route data, it
must always communicate directly with its parent and allow the parent to route data in its behalf.
