“…After handover, the sender restarts the data transmission with the congestion window size which is same as one before freezing data transmission. [10] proposed an inter-domain TCP handover method based on cross-layer and multihoming. This method uses two WLAN interfaces, one for each of the APs (current and new).…”

In wireless LAN environments, the frequency of handover has been increased by the rapid spread of mobile devices such as smartphones and tablets. In such environments, streaming applications such as video feeds, are quite common and have high bandwidth (throughput) requirements. Here, QoS is an important metric for assurance of network quality. QoS-TCP has been proposed as one of the techniques for guaranteeing the throughput; it controls only the terminal. In this study, we treat TCP-AV as one of the typical QoS-TCPs. However, TCP-AV was originally developed for wired networks. It has difficulty in guaranteeing adequate throughput in a wireless LAN environment because it does not consider handover. Given the frequency of handover in wireless LAN environments, (1) we modify the parameters of TCP-AV, and (2) we propose advertise window size control by an access point (AP). Simulation results show that the method proposed herein, which uses both (1) and (2), can attain the necessary throughput, unlike the original TCP-AV approach.

“…Thus, it is not clear that these methods can support the mobile node as the sender. Also, the method in [10] needs to prepare at least two WLAN interfaces and modify both MAC control and TCP control. Equipping the mobile node with multiple WLAN interfaces and modifying MAC control are both difficult.…”
