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。

关键词: 网络编码, TCP / NC 协议, 吞吐率模型, 协议性能, 影响因子

Abstract:

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.

Key words: network coding, TCP / NC protocol, throughput model, protocol performance, impact factors
