Wireless power controlled TCP with holdover
Nicholas Bambos, Kevin Schubert · 2016
Transmission Control Protocol (TCP) has long been used host-to-host over the internet in order to provide reliable and ordered exchange of data. A core component of the protocol is congestion control. Traditional forms of TCP congestion control such as New Reno have been shown to perform poorly over wireless links as a result of non-congestive losses induced by variations in the wireless channel. The fulfillment of the Internet of Things (IoT) will result in more wireless users disadvantaged by asymmetric links as well as power and processing constraints. We consider sender-side protocol adaptations, power control and channel aware congestion window evolution in order to mitigate performance shortfalls for such disadvantaged users. This paper presents a model of these congestion control adaptations, investigates cost tradeoffs, and considers protocol behavior under lossy channel conditions.
