A selection method of optimal channel in wireless network by the dynamic control of the Duty Cycle threshold

Recently, mobile terminals equipped with wireless LAN spread widely. Accordingly, access points such as public Wi-Fi spot or Pocket Wi-Fi come to be used widely. Most wireless LAN is communicated using 2.4GHz bandwidth, but it becomes the problem that the performance of the network decreases because plural terminals use the same channel. This paper intends that access point selects the channel which is most suitable for communication autonomously under the environment where there are a large number of wireless LAN terminals locally. Our proposed method predicts the congestion of the radio wave by analyzing Duty Cycle per each channel and detects the optimal channel. In addition, this method evaluates the quality of communication using expectation of SNR and demanded throughput from SNR. And our method reduces the cost of the channel selection by detecting optimal channel depending on the needs.
