Method and communication system for optimizing the throughput of a TCP flow in a wireless network

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method and communication system to improve the data transmission speed (throughput) of TCP flows in wireless networks. It uses a cross-layer technique, where information about the state of TCP's congestion control is shared from the transport layer down to the data link layer at the wireless transmitter. This allows the system to adapt its data transmission techniques (such as modulation and coding) in real time based on current network conditions, resulting in enhanced overall performance.

Patent Abstract

A method and a system is provided for optimizing the throughput of a TCP flow from a TCP source to a TCP destination in a wireless network with the path of the flow encompassing a wireless link between a wireless transmitter and a wireless receiver. The throughput is optimized by using link-layer mechanisms at the wireless transmitter which are adaptive to the instantaneous TCP dynamics of the TCP flow. In particular, a cross-layer approach is disclosed which serves to tunnel information of TCP congestion control dynamics directly from the TCP based transport layer to the data link-layer which selects in response to these information modulation and/or coding schemas to transmit TCP segments via data link-layer blocks with improved TCP throughput.
