DYNAMIC CHANNEL SELECTION IN IEEE 802.11 NETWORKS

摘要

The present disclosure relates to a method and system for selecting a communication channel from a plurality of available channels in an infrastructure basic service set network having at least an access point and a plurality of access points, the method comprising: monitoring the available channels for a predetermined scan time by a co-located radio station to capture signal level from the plurality of access points at each channel; calculating weighted channel power level of each channel by the processor to determine the channel with minimum power and free channels from the available channels; receiving the signal level of each channel from co-located radio station to processor and calculating weighted channel power level of each channel by a processor to select the communication channel, selecting communication channels comprises: identifying free channels; where there is only one free channel, the free channel is selected, where there is plurality of free channels, the free channel with minimum interference less than a predefined value and with lower weighted channel power level is selected, where there is no free channels, the channel with minimum weighted channel power level is selected. The method provides an improvement of up to 35% in the data throughput in six different real-time network scenarios.
