摘　　要：无线通信网络虚拟仿真实验,在满足大量学生同时操作大型通信网络设备的同时节省了实验室投资和消除了安全隐患。无线网络性能受多方面因素影响,真实网络优化历时较长,难以满足学生实验要求。为了让学生掌握无线网络优化方法的基本原理,基于无线通信网络虚拟仿真实验平台,设计了基于仿真场景参数的优化实验和基于无线参数的优化实验两类,实验方案有助于培养学生分析问题解决问题的能力。对比结果显示,基于虚拟仿真实验平台的无线网络优化实验结果与理论分析结果相一致,实验结果能够验证网络优化方案,可以满足学生实验要求。The virtual simulation experiment of wireless communication network is able to save laboratory investment and eliminate safety hazards while satisfy a large number of students operating large-scale communication network device at the same time.However,the performance of the wireless network is affected by many factors,and the optimization of the real network takes a long time,being difficult to meet the experimental requirements of students.In order to enable students to master the basic principles of wireless network optimization methods,two types of experiments are designed based on the wireless communication network virtual simulation experiment platform,namely optimization experiments based on simulation scene parameters and optimization experiments based on wireless parameters.The experimental program is able to help cultivate students'ability to analyze and solve problems.The comparison results show that the wireless network optimization experiment results based on the virtual simulation experiment platform are consistent with the theoretical analysis results,and the experimental results can verify the network optimization plan and meet the experimental requirements of students.
