摘要
目前移动自组织网中,基于现有的MAC层协议IEEE 802.11 MAC,TCP流之间问公平性很差。严重情况下,一些TCP流的开始会造成另一些TCP流的中断。这些非故障的中断是用户所不能容忍的。本文针对这一问题,采用队列出队速度决定队列出包时间的思想,设计了基于优先级的解决方法。仿真结果表明这种方法能较好的改善TCP流之间的不公平性。
Based on the current MAC protocol IEEE 802. 11 MAC, TCP flows often faces serious unfairness over mobile ad hoc network, which forces some TCP flows to completely stop transferring any data despite all links being in good state. This is not acceptable for users. In the paper, we propose a priority-based method which bases on the idea that the queue output rate decides the time of the output packet. Simulation results show that our scheme can improve the fairness.
