Embodiment Construction

[0022] A wireless relay self-organizing network method with anti-interference performance, the network structure between the host and the node is referred to figure 1 , from node 11 to node NN are all child nodes of the host, node 11 is the parent node of node 21, node 21 is the parent node of node N1, node N1 is the target node, and data packets are transmitted and received bidirectionally along the wireless channel.

[0023] The method includes the following steps: figure 1 — figure 2 ;1) Host initialization: clear the parent node addresses of all nodes, and the host is responsible for issuing all networking commands and activating networking tasks to complete the networking process of all child nodes;

[0024] 2) The first layer of node networking: host networking, the broadcast of the signal strength returned by the host, broadcast network device discovery instructions, all nodes that receive the broadcast reply to the host's local address and signal strength with a rand...

Abstract

The invention discloses a wireless relay self-organizing network method with anti-interference performance. The method comprises the following steps: host initialization; first layer node networking; second layer node networking; other layer node networking; host routing search address table; node routing address table; node sending data packets; relay node forwarding addressing; relay node forwarding exception optimization. Compared with the prior art, the present invention has the following beneficial effects: the present invention realizes the networking without manual setting of nodes one by one, greatly shortens the networking time, and can realize that the host can automatically re-adapt to the group after any node moves. network; at the same time, the efficiency of data packet relay is about double that of traditional single-channel relay technology. The content of the present invention can be widely applied to the collection of terminals requiring large-scale relay, such as street lamps, water and electricity meters, and has good promotion value.

Description

technical field [0001] The invention relates to a relay ad hoc network method, in particular to a wireless relay ad hoc network method with anti-interference performance. Background technique [0002] Existing wireless network technologies are all star-structured networks, which realize communication through fixed network addresses or obtaining network addresses through DHCP, and no direct communication between nodes on the same network segment is required, all of which need to be manually set, forwarded by the gateway, and single-channel networking Slow, low communication efficiency. Contents of the invention [0003] The object of the present invention is to provide a wireless relay ad hoc network method with anti-interference performance aiming at the defects in the prior art. [0004] Its technical solution is: wireless relay ad hoc networking method with anti-interference performance, the method includes the following steps: 1) host initialization: clear the parent n...
