Abstract

The invention discloses a wireless network ad hoc network method and a wireless network ad hoc network system. The method comprises the following steps of: acquiring a coordinate and an address of each node; broadcasting a detection signal through each node to obtain a signal strength value between every two adjacent nodes, and judging connectivity between every two adjacent nodes based on the signal strength values; calculating the distance between every two connected adjacent nodes based on the coordinate of each node; calculating an optimal transmission path from the central node to each node according to the distance between every two adjacent connected nodes, and generating a routing table based on the address and the optimal transmission path; the method comprises the following steps: distributing communication channel parameters to other nodes through a central node according to parameters in a routing table, and sending the parameters in the routing table to the other nodes to generate an ad hoc network of a wireless network; and if the nodes are offline nodes, regenerating a new routing table so as to generate a new ad hoc network of the wireless network. The cost of the whole network can be reduced, and the ad hoc network can be automatically repaired.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless network ad hoc network method and system. Background technique [0002] In environmental monitoring and other related technical fields, there are often scenarios that lack cellular networks. Lora, as a long-distance wireless communication technology, realizes data transmission through the central node through the connection between nodes and data transmission, and has been widely used. The traditional Lora network is a star network structure, that is, a central node is connected to multiple nodes, and each node is not connected to each other. The coverage of this method is limited by the communication distance between the central node and the nodes. [0003] In the prior art, some technical methods are to increase the number of central nodes to achieve the purpose of expanding the communication coverage, and some methods are to increase the relay...
