Embodiment Construction

[0036] The present invention will be further described below with reference to the specific drawings and embodiments.

[0037] A wireless chain network is a network in which a chain or tree topology is formed by wireless nodes; the node described in this invention refers to a communication infrastructure with wireless transceiver and routing capabilities, which can be connected to other wired networks within the signal coverage of the node. Or wireless communication terminals (such as wireless access points AP, cable digital TV, etc.), the nodes described below do not include communication terminals; each node in the wireless chain network of the present invention corresponds to a group (ie GROUP) for Bind the logical scope to which the deployment node belongs, in which the root node is the first node, and other nodes are ordinary nodes. Each group is identified by a unique GROUPID in a CCU subnet group (CLUSTER); a chain or tree composed of multiple nodes The structure can fo...

Abstract

The invention provides a wireless chain network based routing implementation method, which is characterized in that when a node receives a route update message, a routing module combines a self node routing information table, a per-to-peer node routing information table, a self link information table and a peer-to-peer link information table into network bitmap information and sends the route update message to an air interface adjacent node; when the node has peer-to-peer nodes, the routing update message acts as a route sharing message and is sent to all peer-to-peer nodes in the same group; when the node has no peer-to-peer node, the route update message is only sent to the air interface adjacent node; and the node updates the self node routing information table according to a received route update message of the air interface adjacent node, updates the peer-to-peer node routing information table according to a received route update message of the peer-to-peer nodes and updates the self link information table according to a received adjacent node air interface measurement result. According to the invention, the occupation overhead of routing for the air interface can be reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a routing implementation method of a chain-shaped or tree-shaped wireless communication system. Background technique [0002] A wireless ad hoc network is a wireless communication network with no center, self-organization and dynamic topology change. The wireless self-organizing network is divided into topological structures, which can be divided into star networks, such as wireless cellular networks; tree networks, such as some wireless sensor networks; mesh networks, such as wireless mesh networks, different topological structures are applied in the corresponding scene has unique advantages. Wireless chain network is a special topology of wireless self-organizing network. The nodes in the network form a "chain" path. All network nodes together form a chain network. It is used in highways, bridges, tunnels, and street monitoring. In chain-like situations...
