Stochastic Addressing
Zigbee PRO uses a stochastic (random) addressing scheme for assigning the network addresses. This addressing scheme randomly assigns short addresses to new devices, and then uses the rest of the devices in the network to ensure there are no duplicate addresses. When a device joins, it receives its randomly generated address from its parent. The new network node then generates a “Device Announce” frame (which contains its new short address and its extended address) to the rest of the network. If there is another device with the same short address, a router node in the network will send out a broadcast “Network Status – Address Conflict” to the entire network and all devices with the conflicting short address will change its short address. When the conflicted devices change their address, they issue their own “Device Announce” to check their new address for conflicts within the network.
End devices do not participate in the “Address Conflict”. Their parents do that for them. If an “Address Conflict” occurs for an end device, its parent will issue the end device a “Rejoin Response” message to change the end device’s short address and the end device issues a “Device Announce” to check their new address for conflicts within the network.
When a “Device Announce” is received, the association and binding tables are updated with the new short address, but routing table information is not updated (new routes must be established). If a parent determines that the “Device Announce” pertains to one of its end device children, but it didn’t come directly from the child, the parent will assume that the child moved to another parent.
