Abstract
A lot of works on the throughput analysis of the IEEE 802.11 DCF have been studied since last few years. However, we should predict the throughput of the IEEE 802.11g that we mostly use today because the existing numerical results do not consider exactly the IEEE 802.11g with the physical layer ERP-OFDM parameters. In particular, we might have different results in the working WLAN s compared with the simple predictions of the throughput using the previous results. In this paper, we directly monitor the ERP-OFDM physical layer parameters on the operating WLANs, and then analyze the saturated DCF throughput with the well-known analytic model. Moreover, we measure the bandwidth utilization on the real WLANs working with FTP services, and then compare them with the analytic results. According to the experiment results, we confirm the usefulness of the analytic models which assume the saturated traffic sources.
