摘    要:针对无线环境中误码率偏高的特点,着重讨论改善TCP协议性能的方案,并重点研究了纯端到端解决方案中的两种典型TCP协议:TCPW和TCP-Real协议。纯端到端解决方案保持了TCP协议端到端的语义。通过不同误码率下传输性能的仿真,表明两种协议在无线环境下性能均明显优于其他TCP协议。

关 键 词:无线网络    TCP协议    TCPW    TCP-Real    拥塞控制

Abstract:The schemes to solve the high bit error problem in wireless networks were discussed. Aiming to improve the performance of TCP protocal in mobile environments, two typical TCP models of the pure end-to-end approaches, TCPW and TCP-Real, were researched. The pure end-to-end schemes have the advantage of preserving the end-to-end semantics of TCP protocol. Simulation results with different bit error conditions of these protocols reveal an evident improvement in terms of TCP performance in relative to others, especially when the bit error rate is high.
Keywords:wirelesss network  TCP protocol  TCP-Westwood(TCPW)  TCP-Real  congestion control
