Abstract

The embodiments of the present invention disclose an RTS frame transmission rate adjustment method, an RTS frame transmission rate adjustment device, an apparatus and a storage medium. The method includes the following steps that: after the state of an RTS/CTS mechanism is set to be startup, and before a first RTS frame corresponding to current data to be sent is sent, a RTS packet error rate corresponding to a current period is determined according to the RTS packet error rate corresponding to a previous period; and the initial transmission rate of an RTS frame corresponding to the current period is determined according to the RTS packet error rate corresponding to the current period and the initial transmission rate of the RTS frame corresponding to the previous period. With the RTS frame transmission rate adjustment method, the RTS frame transmission rate adjustment device, the apparatus and the storage medium provided by the technical schemes of the embodiments of the invention adopted, the initial transmission rate of the RTS frame corresponding to the period can be adaptively adjusted according to the current interference condition of the transmission path of wireless data, and therefore, the packet error rate of the RTS can be reduced to a certain extent, and the transmission overhead of the RTS/CTS mechanism can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless data transmission, and in particular to a method, device, device and storage medium for adjusting an RTS frame transmission rate. Background technique [0002] The RTS / CTS mechanism is widely used in the field of wireless data transmission to solve the problem of hidden terminals in wireless networks, and can improve the data transmission performance of wireless data transmission devices. [0003] In the prior art, after the RTS / CTS mechanism is started, most of the RTS frames are sent at a relatively fixed rate. It can be understood that although the RTS / CTS mechanism can solve the hidden terminal problem in the wireless network, the mechanism will also generate a certain amount of data transmission overhead. [0004] In the process of implementing the present invention, the inventor found that the prior art has the following defects: the sending rate of the RTS frame ...
