Problems solved by technology

This scheme has convergence oscillation, slow convergence, or even no convergence
However, if channel allocation is performed manually, as the scale of AP deployment becomes larger, the allocation workload will be huge and error-prone. Not only will more labor costs be consumed, but manual planning may also have more uncertainties. For example, AP deployment Mistakes, etc. will cause actual situation and plan to be inconsistent

Abstract

An embodiment of the present invention provides a method for allocating channels in a wireless local area network, which is applied to a wireless local area network including a first AP set composed of at least two APs, including the following steps: determining the neighbor APs corresponding to each AP in the set list, obtain the optimal value of co-channel interference between each AP in the set and each neighboring AP in the neighbor AP list, and the channel value of each AP corresponding to the optimal value, and use the channel value as the AP working channel value. At the same time, the embodiment of the present invention also provides a device for allocating channels in a wireless local area network. The beneficial effect of the present invention is that the channels can be quickly planned, the channels between APs can be automatically and effectively staggered, the same-channel interference of the network itself can be reduced as much as possible, the extra overhead of the network can be reduced, and the network performance can be improved.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and device for allocating channels in a wireless local area network. Background technique [0002] In recent years, the Wireless Local Area Network (WLAN) based on the IEEE 802.11 protocol has developed rapidly due to its outstanding advantages and mature technology, and is widely used in the network construction of shopping malls, enterprises, hospitals, schools and conference venues. [0003] The IEEE802.11 protocol stipulates that WLAN uses two frequency bands of 2.4GHz and 5GHz in ISM (Industrial Scientific Medical), adopts a half-duplex communication mechanism, and provides wireless shared access based on CSMA / CA (Carrier Sense Multiple Access with Collision Avoidance) , that is, in the same area, only one device can send packets exclusively. However, spectrum resources are limited, especially the IEEE802.11b and IEEE802.11g standard wireless networks work in the ...
