Influence of False Congestion Alarms on Performance for Congestion Control Based on Dynamic Window Flow Mechanism in Wireless Networks
White Paper The congestion detection mechanism of congestion control based on dynamic window flow control, which is widely used for reliable window protocols such as TCP, is well-known to be simple, but it may raise false alarms: a sender usually interprets... [03 Jul 2008]
TCP Westwood: End-to-End Congestion Control for Wired/Wireless Networks
White Paper TCP Westwood (TCPW) is a sender-side modification of the TCP congestion window algorithm that improves upon the performance of TCP Reno in wired as well as wireless networks. The improvement is most significant in wireless networks with lossy links. [14 Jan 2008]
TCP-BuS: Improving TCP Performance in Wireless Ad Hoc Networks
White Paper Specifically, the TCP sender concludes that there is network congestion upon detecting packet losses or at time-outs. Hence, the TCP sender could mistake this event as congestion, which is untrue. However, in wireless ad hoc networks, links are... [14 Jan 2008]
Different Mechanism for Improving TCP Performance Over Wireless Links
White Paper The TCP receiver sends cumulative acknowledgments (ACKs) for successfully received segments, which the sender uses to determine which segments have been successfully received. The sender identifies the loss of a packet either by the arrival of... [14 Jan 2008]
Modeling TCP Throughput Over Wired/Wireless Heterogeneous Networks for Receiver-Based ACK Splitting Mechanism
White Paper The mechanism does not need modifications to the sender TCP or the base station. Recently, heterogeneous networks with wired and wireless links are becoming common. However, the performance of TCP data transmission deteriorates significantly over... [26 Dec 2007]
Evaluating TCP With Corruption Notification in an IEEE 802.11 Wireless LAN
White Paper It has been suggested to enhance the performance of TCP over wireless links by adding a checksum that covers the packet header, enabling the TCP receiver to detect errors in the payload and inform the sender of such occurrences. [26 Dec 2007]
De-Randomizing Congestion Losses to Improve TCP Performance Over Wired-Wireless Network
White Paper Currently, a TCP sender considers all losses as congestion signals and reacts to them by throttling its sending rate. This paper proposes a simple biased queue management scheme that "De-randomizes" congestion losses and enables a TCP receiver to... [19 Dec 2007]
TCP With Header Checksum Option for Wireless Links: An Analytical Approach Towards Performance Evaluation
White Paper Basically, the TCP sender responds to these losses as if they were due to congestion in the network, and reduces the congestion window unnecessarily. This paper derives an expression for the probability of a receiver generating successful ELN... [19 Dec 2007]
TCP Westwood: Bandwidth Estimation for Enhanced Transport Over Wireless Links
TCP Westwood (TCPW) is a sender-side modification of the TCP congestion window algorithm that improves upon the performance of TCP Reno in wired as well as wireless networks. The improvement is most significant in wireless networks with lossy links... [06 Dec 2007]
End-to-End Bandwidth Estimation in TCP to Improve Wireless Link Utilization
TCP Westwood (TCPW) is a sender-side only modification of TCP Reno congestion control that exploits an end-to-end bandwidth estimation mechanism to set the values of Slow-Start-Threshold and Congestion-Window after a congestion episode that is... [06 Dec 2007]

TCP Westwood With Bulk Repeat for Heavy Loss Environments
TCP Westwood (TCPW), a recently introduced sender only variant of TCP, was shown to be particularly efficient in high bandwidth, large propagation paths, with light random loss. That is, when the bandwidth delay product is high and some of the... [05 Dec 2007]
