Embodiment Construction

[0024] 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.

[0025] The method includes the following steps: figure 1 — figure 2 ;

[0026] 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;

[0027] 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 ...

Abstract

The invention discloses a wireless relay self-networking method with anti-jamming performance. The method comprises the following steps: host initialization; first-layer node networking; second-layernode networking; other-layer node networking; host route addressing table; node route addressing table; node data packet transmission; relay node forwarding addressing; and relay node forwarding exception optimization. Compared with the prior art, the wireless relay self-networking method has the beneficial effects that networking can be realized without manual node-by-node setting, so that the networking time is shortened greatly, and a host can perform adaptive networking automatically and rapidly once again after movement of any node; and meanwhile, the data packet relaying efficiency is increased by about one time compared with a conventional single-channel relaying technology. The method can be widely applied to terminal acquisition needing large-range relaying such as street lamps and water, electricity and gas meters, and has a good popularization 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: a wireless relay self-organizing network method with anti-interference performance, the method includes the following steps: [0005] 1) Host initialization: ...
