“…TCP Vegas adopts a more sophisticated bandwidth estimation scheme. It uses the measured RTT to calculate the number of data packets, which the sender can inject into the network without incurring packet loss.…”

“…Although TCP Vegas yields both a higher throughput and a lower packet‐loss ratio than TCP Reno does, however, TCP Vegas fails to obtain a fair share of the bandwidth when competing with TCP Reno in heterogeneous networks. Therefore, in, we proposed an adaptive TCP congestion control scheme, which dynamically adjusts the threshold parameters being used to define the congestion window size in such a way as to improve the buffer occupancy of TCP Vegas and thereby increasing its share of the available bandwidth when competing with TCP Reno.…”

SUMMARYWireless technologies provide mobile access and enable rapid andcost‐effective network deployment. But a wireless link is generally accompanied by high interference, transmission errors and a varying latency. The erratic packet losses usually lead to a curbing of the flow of segments on the TCP connection, and thus limit TCP performance. This paper presents a threshold control mechanism with cross‐layer response approach for improving TCP Vegas performance in IEEE 802.11 wireless networks. By making slight modifications to the legacy IEEE 802.11 MAC and TCP, the numerical results reveal that the proposed scheme provides a significant improvement in TCP performance under IEEE 802.11 wireless environments.
