摘要
针对非对称无线网络中,源节点和目的节点之间可能存在多条通信路径,通过计算反向路径带宽和平均吞吐量的关系,提出了将TCP数据报文段和确认报文段(ACK)的传输路径分离的方法。把路径的带宽作为判断标准,选择带宽大的那条路径返回ACK信号。仿真证明了提出的方法可以更加有效地提高TCP吞吐量,增强TCP的性能。
In the asymmetric wireless networks, there are many multi-paths between the source node and the destination node. By calculating the relationship between the reverse path bandwidth and the average throughput, this paper proposes a new method using different paths to transmit TCP data segment and ACK segment. This method uses bandwidth as criteria for judging, and selects the path having lager bandwidth to forward ACK. Simulation result shows that the proposed method can improve the throughput effectively and enhance TCP＇s performance.
