Wireless network uses transmission media based on radio waves. This type of networks is mainly used
due to its efficiency and mobility in data exchanging. This paper reports the modeling and simulation of wireless
networks based on Cisco Aironet 1130ag access point devices with IEEE 802.11a and IEEE 802.11g standards. The
modeling and simulation are performed using network simulator version 2 (NS-2) that is installed on operation
system Linux Ubuntu v.10.10. The NS-2 is commonly used and works well in numerous types of network simulation.
From simulation, we obtain quality of service parameters by employing several simulation scenarios in terms of
number of nodes, distances, and packet data sizes. It can be concluded from simulation results that the IEEE 802.11g
networks transfer data with better quality than those of IEEE 802.11a networks.  Furthermore, the IEEE 802.11g
networks provide a higher throughput, with smaller amount of delay and packet loss percentage compared to those
of IEEE 802.11a networks.
