| 摘 要： | 为了解决实时数据在无线网络中传输中所遇到的拥塞控制问题,结合延迟抖动大小和丢失事件率,对基于用户数据报协议(UDP)的TFRC的拥塞判断机制进行了改进,以使其适用于无线实时传输.改进后的协议减少了因比特传输错误引起的拥塞控制,使得无线实时数据的吞吐率更加平滑.通过NS2仿真环境对改进前后的算法进行了实验对比,结果表明,改进的TFRC协会能为无线实时数据传输提供更好的速率控制策略.

| Abstract: | To solve the congestion control problem of real-time transmission in wireless network, combining delay jitter and loss rate, an improved TFRC congestion control mechanism based on user datagram protocol (UDP) is proposed to adapt to real-time data transmission. The improved protocol reduces congestion control due to bit error in transmission hence provides a more smooth throughput rate in wireless networks. The experimental result compared in NS2 shows the improved TFRC provide a better rate control strateg... |
