| Abstract(in English) | A mobile router (access point: AP) and associated terminals to the AP move together with mobile users. Since a number of Wireless LAN (WLAN) channels is limited when multiple WLANs come close each other, the multiple WLANs may have no choices except using the same channel. In the case, Quality of Services such as throughput can be degraded. This results from both radio interference as well as transport protocol behavior, power saving mechanism, etc. Thus, performance evaluation should be made by using real machines.. In this study, we investigate characteristics of throughput in TCP/UDP flows of real machines when the distance between two WLANs changes. The experimental results shows there are three states in different interference levels and characteristics of individual flow throughput in TCP significantly differ from that in UDP. Moreover, unfairness in individual WLAN throughput occurs if WLANs have different numbers of terminals and flows. In order to mitigate the unfairness, we propose a solution in which greedy TCP is employed instead of normal TCP in the smaller throughput WLAN to mitigate the unfairness and shows effectiveness of the solution. |
