Embodiment Construction

[0052] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0053] This application assigns level information to each network node in the mesh network, and synchronizes the level information to each network node through a private protocol message. Based on the level information, one node is selected as the master node, and the remaining nodes are used as slave nodes. Each node in the network is managed.

[0054] see figure 1 as shown, figure 1 It is a schematic diagram of node level in mesh networking. In the mesh network, the mesh entry node MPP (Mesh Portal point) connected to the external network has a gateway function and can be configured to have the highest level. The level of other nodes is determined according to the level of the previous hop node connected to the node. . The level can be represented by a num...

Abstract

The invention discloses a networking method for wireless mesh network nodes. The method comprises the steps: enabling each node in a wireless mesh network to receive a private protocol message broadcasted by each node in the mesh network, wherein the message at least carries address information of the node and function parameter information; acquiring the function parameter information of each node according to the private protocol message, and selecting the node with the highest level according to a selection strategy; determining the level information of the node relative to the highest level node according to the private protocol message forwarding path jump information, and broadcasting the level information of the node to each node in the wireless mesh network; and determining a mainnode according to the received information of each node level. According to the invention, the modes of the master node and the slave node are formed in the network, and the master node is arranged inthe network, so that the management of the mesh network is facilitated, the natural defects of the mesh network are overcome, and the mesh network is prevented from forming an invalid network.

Description

technical field [0001] The present invention relates to the field of wireless mesh network (mesh), in particular to a method for networking of wireless mesh network nodes. Background technique [0002] The wireless mesh network (mesh) technology is a WiFi network networking method, that is, a mesh network, also known as a "multi-hop" network. Different from the traditional star network topology, in the mesh network, various devices in the network are regarded as nodes, all nodes can be connected to each other, and each node can have multiple connection channels, forming a network between all nodes overall network. Mesh includes mesh networks based on the 802.11s protocol and non-802.11s mesh networks. [0003] The status of each node in the mesh network is equal, and there is no opposing role like AP and terminal (station), which brings great benefits to the network management, data transmission, IP address allocation, and network egress after the establishment of the mesh...
