Improved TCP based on adaptive loss differentiation algorithm over wired-wireless networks

Abstract

BQM discriminator can not be fit to different network states was pointed and an adaptive BQM,whose key idea is adjusting the important parameters for pattern matching according to network states so that the scheme can keep validity while congestion loss and/or channel error increasing was proposed.The experiment results show that the accuracy of ABQM discriminator is higher than BQM in different network states and ABQM can adjust itself adaptively according to network states.ABQM gets better performance than BQM in some metrics,such as network throughput,fairness,delay jitter,and can be implemented and used easily in wired-cum-wireless networks.
