Implementation of Semi-TCP Protocol over Wireless Multi-hop Network
Mei Liu · Jisuanji gongcheng · 2012
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.
