摘要
为提高传输控制协议(TCP)在船舶自组网中的性能,分析暴露终端问题和高负载网络的拥塞控制问题,通过开启定时器的方法对拥塞控制算法进行改进,提出改进的半传输控制协议(Semi-TCP-RTS-V2),并在Exata仿真平台上对TCP-Lite、Semi-TCP-RTS、Semi-TCP-RTS-V2进行性能分析,结果表明,Semi-TCP-RTS-V2在船舶自组网中传输性能有所提高。
In order to improve the performance of transmission control protocol on ship ad-hoc network,the problem of congestion control and exposed terminal in high load network is analyzed,the congestion control algorithm is improved by starting a timer,the semi transmission control protocol named Semi-TCP-RTS-V2 is proposed,and the performance of TCP-Lite,Semi-TCP-RTS,Semi-TCP-RTS-V2 is analyzed in the Exata simulation platform,the results show that the transmission performance of Semi-TCP-RTS-V2 in the ship ad-hoc network is improved.
