The Zigbee protocol, as shown, resides on top of the 802.15.4 PHY and MAC layers and reuses its packet structures. The network diverges at the network and application layers.
The following figure illustrates breaking down one of the 802.15.4 PHY and MAC packets into the corresponding network layer frame packet (NWK) as well as the application layer frame (APS):
Zigbee Network (NWK) and Application Layer (APS) frames residing over 802.15.4 PHY and MAC packets.
Zigbee uses two unique addresses per node:
- Long address (64 bit): Assigned by the manufacturer of the device and is immutable. Uniquely identifies ...
