A comparison of mechanisms for improving TCP performance over wireless links

by Hari Balakrishnan, Venkata N. Padmanabhan, Srinivasan Seshan, Randy H. Katz - IEEE/ACM TRANSACTIONS ON NETWORKING , 1997
"... Reliable transport protocols such as TCP are tuned to perform well in traditional networks where packet losses occur mostly because of congestion. However, networks with wireless and other lossy links also suffer from significant losses due to bit errors and handoffs. TCP responds to all losses by i ..."

Wireless Link.

by Vinayak Abrol
"... When an electronic research succeeds?—when it meets the needs of the people who use it, when it performs flawlessly over a long period of time, when it is easy to modify and even easier to use—it can and does change things for the better. But when it fails—when its results are dissatisfied, when it ..."

When an electronic research succeeds?—when it meets the needs of the people who use it, when it performs flawlessly over a long period of time, when it is easy to modify and even easier to use—it can and does change things for the better. But when it fails—when its results are dissatisfied, when it is error prone, when it is difficult to change and even harder to use—bad things can and do happen.

Analyzing the transitional region in low power wireless links

by Marco Zuniga, Bhaskar Krishnamachari - In First IEEE International Conference on Sensor and Ad hoc Communications and Networks (SECON , 2004
"... Abstract — The wireless sensor networks community, has now an increased understanding of the need for realistic link layer models. Recent experimental studies have shown that real deployments have a “transitional region ” with highly unreliable links, and that therefore the idealized perfect-recepti ..."

TCP Westwood: Bandwidth estimation for enhanced transport over wireless links

by Saverio Mascolo, Claudio Casetti, Mario Gerla, et al. , 2001
"... 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, since TCP Westwood relies on endto-end bandwidth e ..."

Modeling Wireless Links for Transport Protocols

by Andrei Gurtov, Sally Floyd - ACM SIGCOMM Computer Communication Review , 2004
"... Wireless links have intrinsic characteristics that affect the performance of transport protocols; these include variable bandwidth, corruption, channel allocation delays, and asymmetry. In this paper we review simulation models for cellular, WLAN and satellite links used in the design of transport p ..."

Four-Bit Wireless Link Estimation

by Rodrigo Fonseca, Omprakash Gnawali, Kyle Jamieson, Philip Levis
"... We consider the problem of estimating link quality in an ad-hoc wireless mesh. We argue that estimating links well requires combining information from the network, link, and physical layers. We propose narrow, protocol-independent link estimation interfaces for the layers, which in total provide fou ..."
