  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.
