High-density WI-FI covering method

Abstract

The invention discloses a high-density WI-FI (Wireless Fidelity) covering method, and relates to the technical field of communication. The method comprises a WI-FI module group, wherein the WI-FI module group comprises a microprocessor and a WI-FI module, and an ad-hoc network wireless communication module is also arranged on the WI-FI module group. The WI-FI module feeds situations of channel bandwidth back to the microprocessor in real time after a WI-FI terminal is connected to the WI-FI module group, the microprocessor allows the WI-FI terminal to be connected to a network directly through the WI-FI module if the channel bandwidth is expedite, and the microprocessor transfers data of the WI-FI terminal to the ad-hoc network wireless communication module if the channel bandwidth is crowded; and the ad-hoc network wireless communication module sorts WI-FI terminals automatically, and allows the WI-FI terminals to sequentially access the network according to priority values. In comparison with the prior art, the method is applicable to a WI-FI high-density scenario, and when a large number of WI-FI terminals need network connection, the ad-hoc network wireless communication module manages the WI-FI terminals to allow the WI-FI terminals to be connected orderly, keep a WI-FI channel to be expedite, and allow a large number of WI-FI terminals to access the network rapidly in batches.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a channel allocation method in a high-density WI-FI environment. Background technique [0002] In the field of wireless communication, with the development of wireless communication and the popularization of WIFI devices, there are scenarios where hundreds or thousands of WIFI devices need to be deployed. However, whether it is the 2.4G frequency band or the 5.8G frequency band, the number of available channels is often limited. In a high-density scene with thousands of WIFIs (the so-called high-density scene means that there are a large number of WIFI devices in a limited area ), each channel needs to carry a large number of devices, and WIFI devices on the same channel often interfere with each other in the process of sending and receiving messages at the same time, which will lead to a sharp drop in WiFi transmission speed and greatly reduce network performance.

Problems solved by technology

This kind of method has high algorithm complexity, high CPU usage rate during operation, and takes a long time for each channel allocation. The performance is acceptable for a simple network topology and a small number of WIFI devices, but for network topology with relatively Unsatisfactory performance with multiple WIFI devices

Although another algorithm based on the number of neighbors sorts avoids a large number of complicated RSSI value comparisons and improves the speed of channel allocation to a certain extent, its performance still needs to be further improved for high-density scenarios.
