摘要

由于通道的特性，在无线上使用TCP可能会导致性能不佳。当TCP将高误码率和移动主机断开解释为网络拥塞时，会发生显著的吞吐量降低。针对这一问题，我们的研究重点是如何提高TCP在无线网络中的性能。我们研究了使用基础设施网络的移动主机之间的TCP通信。我们引入了一种新的方案，称为MAITE(移动感知合并为TCP增强)，它由一个链路层消息的实现组成，该消息通知TCP高误码率和断开条件。通过模拟，将MAITE方案与其他方案的结果进行了比较。我们的方案使我们的转移时间比其他方案缩短30%。

MAITE: a scheme for improving the performance of TCP over wireless channels

Because of the channel's characteristics the use of TCP over wireless may result in poor performance. Significant throughput degradation occurs when TCP interprets high bit error rate and mobile host disconnections as congestion in the network. We address this problem and focus our research on the study of how to improve the TCP's performance over wireless. We study TCP communications between mobile hosts communicating with each other using an infrastructure network. We introduce a new scheme, called MAITE(Mobility Awareness Incorporated as TCP Enhancement) that consists of an implementation of link layer messages that inform the TCP of high BER and disconnection conditions. By the use of simulations we compare the results obtained with MAITE with other previously proposed schemes. Our scheme provides us with improvements in transfer time of 30% over other schemes.
