Congestion control algorithm for TCP throughput enhancement
Xu Lina · 2011
To enhance TCP throughput in wired/wireless network,a new congestion control algorithm(C-TCP) is proposed based on the constant windows theory.Firstly three phases in C-TCP sender lifetime are analyzed,and a wired/wireless network is designed.Based on NS2 simulation platform,an optimal congestion window for C-TCP is determined and this window is kept constant for the following experiment.Based on no-congestion single TCP link and congestion multiple TCP links,in the context of wireless subnet under both constant bit error rates and burst error,the simulations on throughput are carried out including C-TCP,TCP Reno and TCPW these three algorithms.The results show that C-TCP algorithm is superior to the other two algorithms in throughput.
