| 摘 要： | 异构无线网络中传统TCP协议性能大幅度下降。在不增加开销的情况下,利用三维相位图划分RTT所处空间区域来区分丢包原因,提出了一种新的TCP拥塞控制机制(TCP-BRP)。仿真结果表明,TCP-BRP增强了对拥塞和随机差错的区分能力,满足公平性要求,有效地提高了在异构无线网络环境下TCP的性能。

| Abstract: | The application of TCP over heterogeneous wireless networks is challenged with degressive performance.Without increasing costs,using three-dimensional phase-plot of round-trip-time(RTT) to divide space into several regions in which to distinguish the causation of packets loss,a new TCP congestion control mechanism,TCP based on round-trip-time phase-plot(TCP-BRP) was proposed.Simulation results show that TCP-BRP enhances the distinction ability of congestion and random errors,meets the requirements of fairne... |
