A survey of performance enhancement of transmission control protocol (TCP) in wireless ad hoc networks
This Article is provided by the Brunel Open Access Publishing Fund - Copyright @ 2011 Springer OpenTransmission control protocol (TCP), which provides reliable end-to-end data delivery, performs well in traditional wired network environments, while in wireless ad hoc networks, it does not perform well. Compared to wired networks, wireless ad hoc networks have some specific characteristics such as node mobility and a shared medium. Owing to these specific characteristics of wireless ad hoc networks, TCP faces particular problems with, for example, route failure, channel contention and high bit error rates. These factors are responsible for the performance degradation of TCP in wireless ad hoc networks. The research community has produced a wide range of proposals to improve the performance of TCP in wireless ad hoc networks. This article presents a survey of these proposals (approaches). A classification of TCP improvement proposals for wireless ad hoc networks is presented, which makes it easy to compare the proposals falling under the same category. Tables which summarize the approaches for quick overview are provided. Possible directions for further improvements in this area are suggested in the conclusions. The aim of the article is to enable the reader to quickly acquire an overview of the state of TCP in wireless ad hoc networks.This study is partly funded by Kohat University of Science & Technology (KUST),

How network monitoring and reinforcement learning can improve tcp fairness in wireless multi-hop networks
TCP-Friendly Bandwidth Sharing in Mobile Ad Hoc Networks: From Theory to Reality
This article addresses a problem of the severe unfairness between multiple TCP sessions in a wireless context also known as “TCP capture†phenomenon. We present an adapted max-min fairness framework to the specifics of MANETs. We introduce a practically implementable cross-layer network architecture which enforces our formal model. We have verified with simulations and real world experiments that under our adaptive rate limiting scheme unfair behavior virtually vanishes. The direct consequence of this work guaranteed stable services for TCP-based applications in MANETs, including traditional FTP, web as well as for UDP-based sessions
