The Improvement of Congestion Control Algorithm
Dongdong Liu · Journal of Suzhou University · 2012
Because bit error rate of wireless networks and its packet loss ratio rate are very high,but TCP begins to lower data rate immediately to respond to it when it finds packets are lost,the thought would decline accordingly,then it's necessary to make further analysis of the reason of packets loss,to judge that the packet loss is because of congestion or bit error.RTT could better reflect the current congestion state of network,this paper would use a new method based on RTT to distinguish the packet loss to improve the congestion control algorithm,if the packet loss is because of congestion then the rate should be lowered,if it's because of bit error then it's not necessary to lower rate,only to retransmit the lost packet,which solves the data rate decline because of bit error,so the thought of wireless networks is enhanced.
