ABSTRACT = {The wireless network is limited by the transmission medium, and the
transmission process is subject to large interference and jitter. This jitter can cause
sporadic loss and is mistaken for congestion by the congestion control mechanism. The
TCP Westwood protocol (referred to as TCPW) is such that it cannot distinguish between
congestion loss and wireless jitter loss, which makes the congestion mechanism too
sensitive and reduces bandwidth utilization. Based on this, the TCPW protocol is
modified based on the estimate of the Round-Trip Time (referred to as RTT) value-called
TCPW BR. The algorithm uses the measured smooth RTT value and divides the
congestion level according to the weighted average idea to determine congestion loss and
wireless jitter loss. The simulation results show that the TCPW BR algorithm enhances
the wireless network’s ability to judge congestion and random errors.},
