Abstract:
In IEEE 802.11 wireless LAN, there is a problem that the access point scanning at stations which uses the power management function gives impacts on the performance of TCP communication. In paper, we show the result of experiments on this problem for uploading and downloading TCP data transfer over 802.11n wireless LAN. For the uploading transfer, we analyze the influence to TCP throughput focusing on the TCP small queues that limit the amount of data in wireless LAN's sending queue. As for the downloading transfer, we discuss the influence by the TCP congestion control algorithm at TCP senders and A-MPDU transmission rate at the access point.
