Abstract

The Transmission Control Protocol (TCP) is most important transport layer protocol for the internet access over TCP/IP. The TCP protocol was mainly designed for wired network and it assumes that the packet loss in the network occurs mainly due to congestion only. However, in wireless environment the scenario is somewhat different. As compared to wired link, wireless links are slower and less reliable. Furthermore, characteristic of the wireless network, such as user mobility plays another significant role in packet loss. The loss of packets due to link failure or user movement in wireless part is much more higher compared to loss due to congestion. In this research, we aimed at designing a strategy by extending regular TCP in order to minimize the packet loss and increase throughput to end users. We are specifically targeting a LAN connected users in a moving train and trying to provide reliable connection over TCP session. Few modifications to regular TCP and some new functional components like Mobile TCP Agent (MTA) is proposed to handle TCP session on the train.

一种处理移动车辆局域网TCP连接的新方法

传输控制协议(TCP)是TCP/IP网络访问中最重要的传输层协议。TCP协议主要是为有线网络设计的，它假设网络中的丢包主要是由于拥塞而发生的。然而，在无线环境中，情况有些不同。与有线链路相比，无线链路速度较慢，可靠性也较差。此外，无线网络的特性，如用户的移动性对丢包也起着重要的作用。在无线部分中，由于链路故障或用户移动造成的数据包丢失要比由于拥塞造成的数据包丢失高得多。在本研究中，我们旨在通过扩展常规TCP来设计一种策略，以减少数据包丢失并增加最终用户的吞吐量。我们专门针对移动列车中的LAN连接用户，并尝试通过TCP会话提供可靠的连接。对常规TCP进行了少量修改，并提出了一些新的功能组件，如移动TCP代理(MTA)来处理列车上的TCP会话。
