TCP Vegas-P:Enhanced TCP Vegas congestion control algorithm based on congestion status differentiation over wireless heterogeneous network
Luo Xiao-Shu · Journal of Computer Applications · 2010
In wireless network,channel interference and noise cause significant performance degradation of TCP.In order to solve the problems existing in the application of TCP Vegas,based on TCP New Vegas algorithm,combining the advantages of TCP Vegas A+ algorithm,an improved algorithm named TCP Vegas-P was proposed.It was improved to solve the premature end of the slow start phase and congestion avoidance in the reverse link congestion resulting in the throughput decline,and the fairness deterioration when it was accompanied by NewReno.The simulation results show that the improved algorithm in the wireless network can better estimate Round-Trip Time(RTT),and resolve the problems about Vegas,and can be well applied to wireless network environment.
