Abstract

The invention provides a Beacon frame sending method and device, and the method is applied to first AP equipment, and comprises the steps: scanning a preset wireless channel before a wireless signal is transmitted; when a Beacon frame sent by a second AP device is scanned through the wireless channel, sending the Beacon frame to the second AP device; checking whether the scanned Beacon frame sentby the second AP equipment meets a set Beacon frame mounting condition or not, wherein the Beacon frame mounting condition is that the value of a specified field in the Beacon frame is a first value,and when the value of the specified field is the first value, it shows that other AP devices seize the wireless channel to send the Beacon frame after the second AP device sends the Beacon frame; if so, checking whether the device establishes a Beacon frame mounting relation with the second AP device or not; if so, waiting for a short inter-frame interval SIFS and then sending a Beacon frame of the first AP device on the wireless channel. By applying the method, the Beacon frames sent by different AP devices can be prevented from conflicting on the same wireless channel.

Description

technical field [0001] The present application relates to the technical field of wireless networks, and in particular to a method and device for sending Beacon frames. Background technique [0002] IEEE 802.11 is a common standard for wireless local area networks today, which specifies a media access control mechanism such as DCF (Distributed Coordination Function, distributed coordination function). Under the DCF mechanism, multiple distributed wireless nodes seize the same resource, so the DCF mechanism is a competition mechanism. Because of this, the application of the DCF mechanism in a dense network will have the following defects: [0003] In a dense network, if a wireless node is currently sending a Beacon frame through a wireless channel, then other wireless nodes will wait for DFIS (DCF Interframe Space, distributed coordination function interframe space) and send Beacon frames on the same wireless channel at the same time, by This will cause the Beacon frames of d...
