Basically it differs from TCP Reno in the TCP congestion control algorithm. It was designed by following the principle of Additive Increase Adaptive Decrease (AIAD), not that of additive increase multiplicative decrease (AIMD, used in TCP Reno.
Our simulation considers both the core links and the WLANs. The results show that, TCP Westwood (TCPW) outperforms TCP Reno in terms of average throughput when bursty losses occurred over the wireless channel. The results also show that TCP Westwood (TCPW) is better under bandwidth bottleneck and limited buffer size.
