TCP-H:A new TCP congestion control mechanism based on triple decisions
Zhou Ming · Digital Communication · 2009
The application of TCP over heterogeneous wireless networks is a challenging work due to high bit error rates,fading channels and handoff.Combined with the triple decisions of packet loss detection,the estimation of RTT and the rate of ACK,a new TCP congestion control mechanism(TCP-H)was proposed for heterogeneous wireless networks.The simulation results show that TCP-H can strengthen the capability to distinguish congestion and random errors,and has a good fairness.TCP-H succeeded in solving the problems that Vegas and Westwood had when networks handoff from low-latency to high-latency,with improved minimum RTT calculation method.TCP-H can improve the performance of the heterogeneous networks efficiently.
