Abstract
In a Zigbee network, reliable communications are provided by maintaining messages transmitted from a device in a message queue in the device. If no successful acknowledgement is received for a transmitted message, the message is re-transmitted when the message queue executes. Messages are deleted from the queue when the message is successfully transmitted or when a maximum number of re-tries has been exhausted.
