| Abstract | Bufferbloat is an intractable phenomenon in both the Internet and cellular networks, which may cause excessively long delays without contribution to the improvement of throughput at the same time. The problem matters more for the latter, since large buffer is inevitable due to the demand of link layer retransmission mechanism as well as mitigating traffic burst. We unveil the root cause of bufferbloat to be the mismatching between the adjustment of sending windows and the dynamic variation of available bandwidth at the existence of large buffer. Being the bottleneck link and last hop of a connection in cellular networks, wireless link connects the mobile terminal directly. Besides, the mobile terminal can get all of the information of channel such as channel states and signal strength. So it is more feasible to resolve the bufferbloat at receiver side with the help of channel information, nevertheless, which is ignored in previous studies. So in this article we propose a receiver-based flow control strategy named as ABRWDA that retrieves available bandwidth at receiver side directly and use it to dynamically calculate the receiver window (rwnd) to mitigate the bufferbloat in cellular networks. We test our approach with the NS-2 simulation, and results indicate that ABRWDA achieves 0.1× and 0.4× shorter queues, 0.5× and 0.8× lower latency, while still maintaining the same high throughput as that of Newreno and a previous solution DRWA, respectively. |
