Problems solved by technology
However, the Zigbee protocol does not define the network layer, and its application layer protocol is chaotic, that is, the protocol standards used by various manufacturers may not be consistent. Therefore, the products between manufacturers cannot be used in common before, resulting in certain restrictions on their use.
[0003] In the wireless mesh sensor network under Zigbee technology, most of its communication methods are realized by means of dynamic routing table. The dynamic routing table stores the routing path, and the nodes that transmit data are communicated according to the dynamic routing table. In this way, either need A dedicated storage medium for managing the dynamic routing table is managed in a unified manner, which wastes resources and also causes communication delays, or uses each routing node to manage its own routing path separately, that is, the transmission path between the routing node and all other nodes , when the mesh network reaches a certain scale, the data in the dynamic routing table is very large, which occupies too many resources of routing nodes, which may cause the mesh network to be paralyzed

The invention discloses a communication method of a mesh network based on the Thread protocol, which includes: each routing node creates and maintains a neighbor table, and the neighbor table records the neighbor routing nodes or / and border routers of the routing node; When data is transmitted between any nodes in the mesh network or with the server, the network protocol stack creates a target routing path according to the neighbor table and signal strength, and transmits the data through the target routing path. In the present invention, each routing node only stores and maintains a neighbor table for link connection with other routing nodes and border routers, and saves the resource waste of maintaining the dynamic routing table of the entire mesh network.
Description
technical field [0001] The invention relates to the technical field of wireless networking, in particular to a communication method of a mesh network based on the Thread protocol. Background technique [0002] The existing wireless sensor network is generally networked through the Zigbee protocol. The Zigbee protocol is a short-distance, low-power mesh network communication protocol based on IEEE802.15.4, which defines the network layer and application layer specifications. In the industrial field , commercial lighting and smart home fields have a wide range of applications. However, the Zigbee protocol does not define the network layer, and its application layer protocol is chaotic, that is, the protocol standards used by various manufacturers may not be consistent. Therefore, the products between manufacturers cannot be used in common before, resulting in certain restrictions on their use. [0003] In the wireless mesh sensor network under Zigbee technology, most of its c...
