TCPW improvement based on round-trip delay jitter loss differentiation

In high bit error rate wireless network environment TCP Westwood(for short TCPW) could not differentiate the wireless packet losses from the congestion packet losses.So,a new TCP scheme called TCPW BJ is proposed,which is based on round-trip delay jitter loss differentiation and is a revision of TCP Westwood.It divided network status into different congestion levels by the mea-sured round-trip delay jitter.According to congestion levels,it differentiated the wireless packet losses from the congestion packet losses and carried on the appropriate congestion control.The experiments show that in high bit error rate wireless networks TCPW BJ algorithm significantly improves bandwidth utilization and throughput,and maintains the fair and friendly behavior with respect to other TCP flows.
