摘要:
该文介绍了 802.11 无线网络协议的类型, 详细分析了 NS-3 的主要组件和仿真过程。利用 NS-3 仿真平台编写仿真脚本, 模拟实现 Sta-AP 和 ad hoc 网络在不同的网络拓扑结构中的性能状况,通过调整 AP 数量和节点移动速度设置不同的网络环境,并在网络节点上加载不同的路由协议,调整不同的网络性能参数,对 NS-3 平台特点有了更深的认识。 利用 Wires hark 和 NS-3 平台的 Flow Monitor 方法获取网络性能数据,通过对比分析 Flow Monitor 和 Wires hark 监测流量的差距,发现 Flow Monitor 方法本身的局限性,从而有助于现实环境中更科学地选择网络协议部署网络环境。 借助于高效的仿真分析平台,最终得到一系列有价值的实验结果,为下一步研究奠定了良好的实践基础。
Abstract:
We introduce the types of 802. 11 wireless network protocols and analyze the main components and simulation process of NS-3 in detail.? ? The simulation script is written by NS-3 simulation platform to simulate the performance of Sta-AP and ad hoc networks indifferent network topologies. By adjusting the number of AP and the speed of nodes to set different network environments, loading different routing protocols? on network nodes,and adjusting different network performance parameters, we have a deeper understanding of the characteristics of NS-3 platform. Using Wire shark and Flow Monitor method provided by NS - 3 platform to obtain network performance data,the limitations of Flow Monitor method are found after the comparative analysis of the gap between Flow Monitor and Wire shark. It is helpful to choose network protocol for deployment network environment more scientifically in real environment. With the help of efficient simulation and analysis platform,a series of valuable experimental results are finally obtained,which lays a good foundation for further research.
