A Novel TCP Congestion Control Mechanism for Wireless Network
Xiaoli Wang · Beijing Youdian Xueyuan xuebao · 2005
The optimal value of the TCP(transport control protocal) data sending rate was studied when the wireless channel was in bad state.Two algorithms to adjust the size of TCP CWND(congestion window) were presented.The target of most research on TCP in wireless network is to improve the throughput.So the size of CWND doesn't decrease when the packet loss is due to corruption.The result is the decrease of the reliability of TCP when the heavy packet loss rate occurs.The requirement of throughput and reliability were studied.The simulation results demonstrate that the QoS(quality of service) requirement is met and the throughput is not declining greatly.
