Since traditional TCP timer is fundamentally inappropriate for ad hoc network with random abrupt round-trip time(RTT),a new TCP timing scheme based on rtt_active timer was proposed.
针对传统的TCP定时器不适用于具有动态随机变化往返时间的ad hoc网络,提出了一种基于rtt_active定时器的新的TCP定时方案。

This paper presents two new mechanisms to improve the performance of wireless TCP,they are:the scheme of adjusting TCP s segment size based on retransmission ratio and the scheme of setting Round Trip Time (RTT) threshold based on estimated throughput.
本文提出了两种无线TCP改进机制 ,即 :基于重传率调整TCP段尺寸的机制和基于吞吐量估计设置往返时间 (RTT)门限检测网络拥塞的机制 。
