Node accessing method of Zigbee network

Abstract

The invention discloses a node accessing method of a Zigbee network. The node accessing method comprises the steps of broadcasting node information of a to-be-accessed node through a coordinator; receiving the node information and writing the node information into an address pool by a router node, starting a networking allowing function and reporting a state parameter to the coordinator; receiving the state parameter by the coordinator, and setting priority of each router node according to the state parameter; broadcasting a beacon frame by the to-be-accessed node; performing matching between the node information in the beacon frame and the node information in the address pool by the router node which receives the beacon frame, and when matching is successful, transmitting a response allowing request to the coordinator; selecting the router node with highest corresponding priority as a target router node by the coordinator according to the received response allowing requests, and allowing transmission of a response frame from the target router node to the to-be-accessed node; and receiving the response frame by the to-be-accessed node and accessing the target router node. The node accessing method settles a problem of incapability of correctly assigning a Zigbee network address on the condition of different keys, thereby preventing data exchange of illegal equipment radically.

Description

technical field [0001] The invention belongs to the technical field of smart home, and in particular relates to a node access method of a Zigbee network. Background technique [0002] ZIGBEE technology uses 802.15.4 to define the physical layer and MAC layer, and supports Mesh topology. It has the characteristics of large network capacity, excellent network topology capability, simple network deployment, and low power consumption. Its coverage in the field of the Internet of Things has also spread rapidly, and its application occasions have gradually covered the field of household appliances from the field of urban construction. [0003] Home appliances of different home appliance manufacturers usually have their own communication or control protocols. In order to realize the interconnection and interoperability of devices from different manufacturers, all major smart home application manufacturers are moving closer to a certain standard protocol. [0004] However, the im...

Problems solved by technology

[0006] Although the ZIGBEE protocol itself also has an encryption mechanism, devices with different keys cannot communicate normally, but its encryption mechanism works on the APS layer, so even if the keys of the two devices are different, the network address can be correctly assigned, the difference lies in the devices with different keys Incapable of normal data interaction, ZIGBEE technology also withdraws devices with different keys that are correctly assigned addresses

Therefore, although technologies such as short-distance networking and button networking can alleviate unnecessary troubles to a certain extent, they cannot solve fundamental problems, such as: residential owners separated by a wall, rogue nodes that frequently initiate network access requests, etc.
