Abstract (in Japanese) (See Japanese page) 
(in English) Network congestion is a prevalent problem on the Internet. Modern loss-based TCP algorithms aim to increase throughput by using aggressive congestion window (CWND) control strategies. Due to such strategies, a large number of packets may be backlogged and eventually dropped at the entry point to a wireless access network. Our previous work proposed CUBIC-based CWND control middleware for Android terminals to solve the backlog issue. It utilizes Round Trip Time (RTT) as an indication of the TCP ACK backlog condition at the WLAN Access Point (AP), and controls the upper and lower bounds of its CWND size to suppress excessive transmissions of its own TCP DATA packets. However, the middleware causes the severe fairness dwindling due to the timing difference of the middleware of each node when to start the control. In this study, we propose a new mechanism which takes the fairness of the transmission into account. Our new method starts control with taking cooperativeness into account. Our evaluation demonstrated that our new method gained more cooperativeness and fairness over the previous one by comprehending the situation of all other competing devices in the network.
