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 A
B
QM discriminator is higher than BQM in different network states and A
B
QM can adjust itself adaptively according to network states.A
B
QM 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.
