Method and system for adjusting energy consumption of multi-channel wireless network

Abstract

The invention provides an energy consumption adjusting method of a multichannel wireless network which densely deploys APs (Access Point) through space. The method comprises following steps of periodically obtaining the association relations and average signal strength of each terminal at the AP locations of different service areas of each channel layer; adjusting the terminals associated among different channel layers according to the number of the terminals associated with the APs of different channel layers; adjusting the terminals associated among the different areas of the channel layer according to the number of the terminals in the same channel layer associated with the APs of different areas; and independently adjusting the wireless transmitting power of each AP.

Description

technical field [0001] The invention relates to wireless communication, in particular to a method for access control of a wireless network. Background technique [0002] In order to solve the problems of co-channel interference, limited access scale and performance in the network deployment of traditional wireless networks, the wireless architecture of virtual cells can usually be adopted. For an enterprise-level wireless network, the wireless architecture of virtual cells can usually be further divided by using multi-layer channels. [0003] In a wireless network combined with a virtual cellular network and a multi-channel layer, it includes: at least one controller and multiple access points (Access Point, AP). The controller can be connected to the wireless network in any manner, and each AP can use the same service set identifier (Service Set Identifier, SSID). The APs are divided into multiple groups, and the APs in each group use channel layers that do not interfere ...

AI Technical Summary

Problems solved by technology

[0005] Generally, in order to increase the capacity of the wireless network and obtain better signal coverage, APs are deployed at a general density, but this will make the signal transmission rate at the edge of the AP coverage lower.

Relatively, the way of deploying APs in a high density and simply pursuing signal coverage will cause a large energy consumption of the entire wireless network system, and will cause conflicts between more adjacent terminals on the same channel
