The present invention relates to the smart home field and discloses a node of a wireless network and a status updating method thereof. In the present invention, each node in the wireless network periodically sends status broadcast message according to the preset period, and the status broadcast message at least carries the identifier and current status information of the present node. The nodes receiving the status broadcast messages record the current status information of the other nodes carried in the received status broadcast messages, wherein the recorded current status information of the other nodes is carried in the sent status broadcast message if the each node in the wireless network has received the status broadcast message of the other nodes when needing to send the status broadcast message. In the present invention, the nodes in wireless network can periodically send status broadcast message carrying the received current status information of the other nodes, such that it can automatically update status of the device nodes in the smart home system and improve the user experience.
