| Abstract(in English) | In heterogeneous wireless networks which have various kinds of radio access networks (RANs), it becomes possible to improve QoS by using the best connections. In order to optimize the throughput, link aggregation techniques have been applied by aggregating different RANs. However, when different RANs which have different QoS are aggregated, the link aggregation throughput degrades in TCP communications. In this paper, to overcome such difficulties, we propose a scheme which improves the link aggregation throughput by traffic distribution ratio optimization based on the QoS parameters of each RAN. We use an experimental wireless network system, which has a wireless link aggregation function using TCP capsuling, and measure the TCP throughput improvement over the aggregated wireless link by setting to optimal traffic distribution ratios. By our experiments, we show that the aggregation throughput is seriously degraded by difference on QoS parameters, such as link throughput, delay, jitter, and packet loss, and clarify that our scheme improves the aggregation throughput by optimally setting the traffic distribution ratio. |
