摘要
为改进传统传输控制协议(TCP)在无线网络中的性能,运用Matlab对TCP Reno,TCP Vegas和基于网络编码的TCP/NC吞吐率分析模型进行数值求解,分析3个模型在不同网络环境下应达到的理论值,验证TCP/NC模型在理论上能否提高其吞吐率。基于NS-2对3种吞吐率模型进行仿真,结果表明,TCP/NC及其分析模型可有效改进TCP协议。
In order to improve the traditional Transmission Control Protocol（ TCP） performance in wireless networks, this paper solves throughput rate model of three TCP protocols,TCP Reno,TCP Vegas and TCP/NC based on network coding through Matlab,and analyzes the theoretical value of the three models in different networks,and verifies whether TCP/NC model can improve its throughput rate. The three models are simulated through NS-2,and simulation results show the effectiveness of TCP/NC protocol and its analysis model.
