| 摘 要： | 为解决传统TCP协议在无线多跳网络中经常误判网络拥塞状况且反应迟钝的问题，提出一种Semi-TCP协议的实现方法。添加虚拟TCP层控制包的过滤和重发，采用逻辑信道传递跨层信息，应用一跳式ACK速率控制策略调节发送速率。仿真实验结果表明，该实现方法能在不改变原TCP协议框架的基础上提高系统性能。

| Abstract: | Original TCP protocol often misjudges the congestion status and reacts slowly in wireless multi-hop networks,and this paper proposes an implementation method of Semi-TCP protocol.It uses a Virtual TCP(VTCP) layer to control the filter and retransmission of the packets,a logical channel designed to deliver cross-layer information,and a rate adjustment mechanism with one-hop ACK packet.Simulation experimental results show that this method can improve congestion control performance without changing original TCP framework. |
