Title: The congestion control mechanism in wireless networks by cross-layer optimization based on the adaptive bandwidth estimation
Abstract: TCP is the transmission layer protocol which actively explores available network bandwidth.One of the ways of TCP modification is based on estimation of the available bandwidth and adjustment of the transmission window.In this paper,a novel TCP congestion control mechanism is proposed using adaptive bandwidth estimation in wireless networks which continuously measures the bandwidth via monitoring the rate of ACKs and RTT values.Based on the estimation of the available bandwidth,this scheme dynamically adjusts the congestion window and realizes the adaptive parameter setting of the slow start threshold.Simulation results show that the probability of multi-packet loss has been significantly decreased and TCP performance has been effectively improved by implementation of this scheme.
