Method for selecting wireless relay in low-frequency-stage and low-power-consumption wireless local area network

Abstract

The invention discloses a method for selecting a wireless relay in a low-frequency-stage and low-power-consumption wireless local area network. The method includes the steps that firstly, ordinary stations collect information of available relay stations; secondly, the relay stations send data reported by the ordinary stations to access points through detection motion report frames; thirdly, the relay stations are distributed to the ordinary stations respectively through the access points; fourthly, the access points inform the ordinary stations of the distribution result obtained in the third step. According to the method, a least number of relay stations can be used, competition for channels among the stations can be reduced, and the use ratio of bandwidth resources can be improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method for common stations to select relay stations in a wireless local area network with low frequency band and low power consumption. The relay site effectively utilizes the bandwidth resources of the network. Background technique [0002] In a wireless local area network, due to the different location distribution of each common station, the distances between them and the access point and the relay station are not the same. Ordinary stations will detect access points or relay stations that can be connected in the nearby area by receiving beacon frames. Some ordinary stations can only detect one relay station, and some ordinary stations can detect two or more relay stations. [0003] Generally, ordinary stations select the relay stations they want to connect to according to the signal strength. This method of selecting relay stations for ordinary statio...

AI Technical Summary

Problems solved by technology

[0003] Generally, ordinary stations select the relay stations they want to connect to according to the signal strength. This method of selecting relay stations for ordinary stations has certain defects. Common stations in the network cannot use the least number of relay stations, and some relay stations do not have to be used. and the common sites do not know the current connection status of the relay sites, so some relay sites will connect to a small number of common sites, and some will have a large number, which is very unbalanced

When some relay sites that are not necessary to be used are added to the connection, the number of competitions for channel resources will be increased, resulting in a waste of bandwidth resources
