摘要

A VLAN is a logical rather than physical connection that allows grouping hosts together in thesame broadcast domain, so that packets are only delivered to ports that are combined to thesame VLAN. By characteristic VLAN network, we can improve efficiency of wireless networkand save bandwidth. Furthermore, implementing VLAN greatly improves wireless networksecurity by decreasing the number of hosts that receive copies of frames broadcasted byswitches, so hosts holding critical data are kept on a separate VLAN. This paper compareswireless network with wireless network having VLAN deployment. The proposed Network isevaluated in terms of average throughput and delay using file transfer in heavy traffic and webbrowsing applications. The simulation was carried out by employing OPNET 14.5 modelersimulation and the results show that the use of VLAN via wireless network had improved theperformance by decreasing the traffic resulting in minimizing delay time. In addition,implementing VLAN reduces the network throughput because the traffic that is received andforwarded has a positive relationship with throughput. Furthermore, we investigated toimprove the throughput in a wireless VLAN network by using adhoc routing protocols.Evaluation, comparison of broad adhoc routing protocols like AODV, DSR, OLSR, TORA andGPR are conducted in order to show the effect of the proposed VLAN on the performanceresults, like throughput and delay.
