Embodiment Construction

[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0039] see figure 1 , figure 1 It is a network architecture diagram of the wireless communication system of the present application, and the wireless communication system includes:

[0040] A router (router), an access point (access point, AP for short) and multiple stations (station, STA for short), and the router serves as a gateway between the AP and the Internet (Internet). An AP and multiple nearby STAs form a tree communication network, and the tree communication network includes two types of nodes: parent nodes and child nodes. AP is the root node of the tree-shaped communication network, the root node is a special parent node, and the root node has only child nodes. The tree-shaped communication network has at least one layer, and...

Abstract

The embodiment of the invention discloses an ad hoc network method and device based on WiFi, a storage medium and a wireless node, and belongs to the field of wireless communication. The method comprises the following steps: when a first node searches a child node, the first node broadcasts a beacon frame; the first node receives a connection authentication request sent by the second node in response to the beacon frame; the first node obtains a network topology parameter, wherein the network topology parameters comprise the number of child nodes of the first node and the depth between the first node and a root node; and when the network topology parameter is matched with a preset networking constraint parameter, the first node and the second node establish WiFi connection to enable the second node to serve as a child node of the first node, and the topology structure of the communication network can be flexibly adjusted according to different application scenarios.

Description

technical field [0001] The present application relates to the field of wireless communication, in particular to a WiFi-based ad hoc network method, device, storage medium and wireless node. Background technique [0002] The self-organizing network is a temporary multi-hop autonomous system composed of multiple nodes with wireless transceiver functions. It does not depend on the preset infrastructure and has the characteristics of temporary networking, rapid deployment, no control center, and strong invulnerability. And other characteristics, in the military and civilian aspects and civilian aspects have broad application prospects. How to conduct ad hoc networking based on WiFi communication to obtain a stable and reliable tree-shaped communication network is a current research hotspot. Contents of the invention [0003] The WiFi-based ad hoc network method, device, storage medium, and wireless node provided in the embodiments of the present application can solve the prob...
