Method of TCP Performance Enhancement in Asymmetric Wireless Networks

摘要

There may exist multi-path between the source node and the destination node in asymmetric wireless networks. By calculating the throughput, this paper proposes a new method which determines whether to use 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 advance TCP performance.
