Embodiment Construction

[0061] 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.

[0062] The applicant found that the mesh network based on the 80211s protocol has the characteristics of too free networking, decentralization, and complete equality between all nodes in the mesh network, which adds difficulties to the practical application of mesh:

[0063] ①Due to the characteristics of the 802.11s protocol itself, there are great obstacles when mesh nodes switch channels, and they cannot automatically follow the channel of the access point like ordinary WiFi stations. Once the channel is switched, it is easy to split into multiple invalid small LANs and cannot be recovered.

[0064] ②The mesh network is a mesh network, which can have multiple links at the same time, and there are many possible data transmission links. Once the network has a p...

Abstract

The invention discloses a management method of a wireless mesh network, the wireless mesh network comprises a master node and more than one slave node, and the method comprises the following steps: ona master node side, communicating with the slave nodes based on a network management protocol message, and performing one or any combination of first management of network heartbeat synchronization between the master node and the slave node, second management of routing information synchronization and third management of a network health state on the wireless grid network. A signaling channel isprovided for information synchronization, command transmission and updating among all the nodes in the network, self-management, self-maintenance, self-repair and self-optimization of the network arerealized, and the pain caused by the characteristics of excessively free networking mode, decentralization and complete equivalence of the status among all the nodes in the mesh network in the mesh network is solved.

Description

technical field [0001] The present invention relates to the field of wireless mesh network communication, in particular, to a management method and device for a wireless mesh network. 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 difficulties to the self-management of the network itself after the establishment of the mesh network. Contents of the...
