Embodiment Construction

[0036] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0037] The wireless chain network is a network composed of wireless nodes in a chain or tree topology; the nodes described in this invention refer to communication infrastructure with wireless transceiver and routing capabilities, and other wired networks can be connected within the signal coverage of this node. Or wireless communication terminals (such as wireless access point 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, where the root node is the head 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 link structure can form a link (L...

Abstract

The invention provides a routing implementation method based on wireless chain network. When a node receives a routing update message, the routing module uses its own node routing information table, peer node routing information table, its own link link information table and peer-to-peer The link link information table is combined into reachable network bitmap information, and the routing update message is sent to the adjacent node of the air interface; when the node has a peer node, the routing update message is sent to the same group as a route sharing message All peer nodes; when there is no peer node, only send a routing update message to the adjacent node of the air interface; the node updates the routing information table according to its own node according to the routing update message received from the adjacent node of the air interface, and according to the received peer node The routing update message updates the routing information table of the peer node, and updates the link information table of its own link according to the received air interface measurement result of the adjacent node. The invention can reduce the occupation cost of the air interface of the route.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and specifically relates to a routing realization method of a chain or tree wireless communication system. Background technique [0002] A wireless ad hoc network is a wireless communication network with no center, self-organization, and dynamically changing topology. The wireless ad hoc network can be divided into star network, such as wireless cellular network; tree network, such as some wireless sensor networks; mesh network, such as wireless mesh network, different topological structures are applied in corresponding The scene has unique advantages. Wireless chain network is a special topology structure of wireless self-organizing network. The nodes in the network form a "chain" path, and all network nodes together form a chain network. It is used in highways, bridges, tunnels, and street monitoring. For chain occasions such as border security, it can reduce unnecessar...
