网络仿真通过权威的网络仿真软件系统,利用普通微机平台,可针对各类无线网络进行多个项目的试验,不再受经费、场地、设备等的影响。学生还可通过仿真软件提供的动画演示功能,直观形象地了解各种无线网路协议的原理和功能,改善学习效果。本文介绍了网络仿真软件NS2的工作原理和特点,探讨了NS2在网络教学中的应用,并给出了应用实例。 Network simulation through the authority of the network simulation software system, the use of ordinary microcomputer platform for a variety of wireless networks for more than one project test, no longer subject to funding, space, equipment and so on. Students can also use the animation demo provided by the simulation software to visually understand the principles and functions of various wireless network protocols and improve the learning effect. This paper introduces the working principle and characteristics of the network simulation software NS2, explores the application of NS2 in the network teaching, and gives the application examples.
