Wireless relay networking data transmission method taking group as unit

Abstract

The invention discloses a group-based wireless relay networking data transmission method, which comprises the following steps that: all wireless devices are divided into a plurality of groups, and routing tables are configured in all the wireless devices; data information sent by a sending wireless device is sent, all wireless devices in the sending range of the sending wireless device are receiving wireless devices, and the receiving wireless devices receive the data information sent by the sending wireless device; when the self device address of the receiving wireless device is the same as the device address of the to-be-transmitted target device in the data information, the receiving wireless device reads the to-be-transmitted data, and transmission is finished; otherwise, when the receiving wireless device is a relay device, repeating the above steps by taking the receiving wireless device as a new wireless transmitting device; and when the received wireless device is not the relaydevice, discarding the received data information. The data transmission method provided by the invention has higher reliability, and the anti-interference capability of wireless data transmission isimproved.

Description

technical field [0001] The invention belongs to the field of data transmission, and relates to a wireless relay network data transmission method with a group as a unit. Background technique [0002] With the development of the Internet of Things in various fields, short-distance wireless communication technology is becoming more and more mature. The most commonly used method is 2.4G wireless communication, which has the advantages of low power consumption, anti-interference ability, and high security, and is widely used in people's lives. middle. [0003] However, the distance of 2.4G wireless communication is generally relatively short; the ability to penetrate walls is poor, and it is easily interfered by obstacles such as walls; it is easily interfered by other wireless signals in the same frequency band. If the distance between the two devices is too far or there is an obstacle, the communication may be blocked or the stability of the communication capability may be poo...

Problems solved by technology

[0003] However, the distance of 2.4G wireless communication is generally relatively short; the ability to penetrate walls is poor, and it is easily interfered by obstacles such as walls; it is easily interfered by other wireless signals in the same frequency band

If the distance between the two devices is too far or there is an obstacle blocking, the communication may be blocked or the stability of the communication capability may be poor

Moreover, most of the occasions where wireless communication equipment is used are more complicated, and there are many obstacles.
