| Abstract(in English) | The IEEE 802.11n wireless local-area network (WLAN) has become popular for the Internet access due to simple installations, low cost devices, and easy extensions. Unfortunately, dense installations of access points (APs) in a network field can cause high radio interference, and may result in poor performances. To address the issue, we have studied the AP interface setup optimization method for concurrently communicating APs in WLAN. To maximize the total throughput, it selects the channel and the transmission power of either maximum or minimum, such that the average signal-to-interference ratio (SIR) among all the APs becomes largest. However, the receiving signal strength (RSS) needs to be measured under any possible combination before the selection, which increases loads and time when the number of APs increases. Besides, only the channel bonding (CB) is considered, although non-CB sometimes gives better performances under high interferences. In this study, we study the feasibility of the method by estimating SIR using the throughput estimation model that we presented before, including the selection of CB or non-CB for WLAN with three APs. This model approach can avoid costs of a lot of RSS measurements even if the number of APs increases more. We compare the results with the throughput measurement results using Raspberry Pi APs under various network topologies, and confirm that the model can successfully select the best AP interface with the highest total throughput. |
