Abstract
In this paper, we propose a user cooperative mobility to improve Transmission Control Protocol-Bottleneck Bandwidth and Round-trip propagation time (TCP-BBR) throughput. In a single-flow ad-hoc network with TCP-BBR traffic, the TCP-BBR does not work well due to the variation of Round-Trip Time (RTT). By considering the fact that TCP-BBR does not work well, the proposed Data suppression Acknowledge character (ACK) retention method stabilizes the RTT and improves the Wireless Local Area Network (WLAN) bandwidth at the same time. After giving an overview of the proposed method, we show the results of evaluating the throughput characteristics by NS3 simulation. The results show that the proposed method successfully improves the throughput by up to 232% compared to the throughput before moving, which is better than the conventional method, demonstrating the effectiveness of the proposed method.
