Embodiment 1

[0058] Embodiment 1 of the present invention provides a routing management method based on a Mesh network, such as image 3 As shown, the method includes the following steps:

[0059] Step 301, the routing management node that constitutes a peer-to-peer network with other routing management nodes broadcasts routing messages in the mesh network; wherein, the routing management node can be a separate mesh network node, or an existing mesh network node with routing information. The nodes of the management function module, the routing management node is only a part of the nodes in the mesh network, and is used to manage the routing of the mesh network;

[0060] Step 302, the routing management node receives and saves the registration information returned by the normal Mesh node according to the routing message, and performs routing management on the normal Mesh node registered on the routing management node, and the registration information includes the normal Mesh node The routi...

Embodiment 2

[0064] The routing management method based on the Mesh network provided by Embodiment 2 of the present invention will be described in detail below, as Figure 4 shown, including:

[0065] Step 401, each routing management node broadcasts routing messages in the Mesh network, wherein the routing management nodes form a peer-to-peer network;

[0066] Embodiment 2 of the present invention utilizes the characteristics of large communication bandwidth and small time delay of wired channels. Preferably, in a Mesh network, a wireless Mesh router that is fixedly connected to a wired channel is used as a routing management node; optionally, the aforementioned routing management node It can also be other network entities in the Mesh network; wherein, the route management node is a part of the nodes in the Mesh network, and is responsible for the route management of the Mesh network.

[0067] In Embodiment 2 of the present invention, the routing management node may constitute a structur...

Embodiment 3

[0082] The routing management method based on the Mesh network provided by Embodiment 3 of the present invention, such as Figure 5 As shown, the method includes:

[0083] Step 51, the ordinary Mesh node acquires the routing cost from the ordinary Mesh node to each routing management node according to the received routing message;

[0084] Step 52, the ordinary Mesh node determines the routing management node with the smallest routing cost with the ordinary Mesh node according to the routing cost, and obtains the shortest routing path, and the shortest routing path is from the ordinary Mesh node to the The routing path of the routing management node determined above;

[0085] Step 53, the common mesh node sends registration information to the determined routing management node, and accepts the routing management of the routing management node, the registration information includes the shortest routing path of the common mesh node and the normal mesh node address information....

Abstract

The invention discloses a Mesh network-based routing management method, a routing management node, a node, a Mesh network-based routing method, a communication device and a communication system, which relate to a communication network technique, can improve the velocity of routing discovery, and reduce the routing time delay. The Mesh network-based routing management method comprises the following steps that: a routing management node which forms a peer-to-peer network with other routing management nodes broadcasts a routing message in the mesh network; and the routing management node receives and stores the registration information which is returned by a common Mesh node according to the routing message, and carries out routing management on the common Mesh node which is registered on the routing management node, wherein the registration information comprises a routing path with the minimum routing cost in at least one routing path between the common Mesh node and each management node, and the address information of the common Mesh node.

Description

technical field [0001] The present invention relates to communication network technology, in particular to a Mesh network-based routing management method, routing method, routing management node, node, communication device and communication system. Background technique [0002] Wireless Mesh Network (WMN), also known as Multi-hop Network, is a new type of wireless network. Each node in the network can send and receive signals, and each node can communicate with a Or multiple peer nodes communicate directly. [0003] There are three types of network structures used in wireless mesh networks: planar structure, hierarchical structure and hybrid structure. Among them, such as figure 1 As shown, the hybrid structure is the most commonly used networking structure of the wireless mesh network. The wireless mesh network with hybrid structure is composed of mesh (Mesh) client 11 and mesh (Mesh) router 12, Mesh client 11 accesses the Mesh backbone network through Mesh router 12, and...
