A new approach to improve transport control protocol (TCP) throughput in wireless networks was proposed, in which the detecting and retransmission of lost packets are performed by ARQ (Automa tic Repeat ReQuest) in data link layer.

• 针对现有提高无线网络中传输控制协议 ( TCP)吞吐量方案 (如 Snoop)的若干局限性 ；提出一种改进方案 ；利用数据链路层的自动请求重传 ( ARQ) ；检测并重传在无线链路上丢失的分组 ；从而提高 TCP的吞吐量性能 .
