论文摘要
VLAN是一种逻辑连接，允许主机在同一广播域中分组在一起，因此数据包仅交付到合并到同一VLAN的端口。我们可以通过特征VLAN网络来提高无线网络性能并节省带宽。此外，VLAN的实现通过减少接收由交换机播放的帧副本的主机的数量来大大提高无线网络安全性，从而使主机在单独的VLAN上持有关键数据。在本文中，我们将无线网络与通过无线网络进行比较。使用Web浏览应用程序和流量中的文件传输在延迟和平均吞吐量的范围内评估所提出的网络。使用OPNET 14.5建模者进行了仿真，结果表明，通过无线网络使用VLAN通过减少流量，从而改善了性能，从而最大程度地减少了延迟时间。此外，VLAN实施减少了网络吞吐量，因为接收到的流量与吞吐量具有正相关关系。最终，我们研究了ADHOC路由协议（例如AODV，DSR，OLSR，Tora和GPR）的使用来提高无线VLAN网络的性能。
A VLAN is a logical connection that allows hosts to be grouped together in the same broadcast domain, so that packets are delivered only to ports that are combined to the same VLAN. We can improve wireless network performance and save bandwidth through the characteristic VLAN network. In addition, the implementation of VLAN greatly improves wireless network security by reducing the number of hosts receiving copies of frames broadcast by switches, thus keeping hosts holding critical data on a separate VLAN. In this paper we compare wireless network with VLAN via wireless network. The proposed network is evaluated within terms of delay and average throughput using web browsing applications and file transfer in heavy traffic. The simulation was carried out using OPNET 14.5 modeler and the results show that the use of VLAN via wireless network improved performance by reducing traffic resulting in a minimized delay time. Furthermore, VLAN implementation reduces network throughput because the traffic received and transmitted has a positive relationship with throughput. Eventually, we investigated the use of adhoc routing protocols such as AODV, DSR, OLSR, TORA and GPR to improve the performance of wireless VLAN networks.
