Network parameters are vital ingredients of today's data communication scenario especially Media access delay, Throughput and CPU utilization. This Paper has taken into consideration the modeling and implementation of Wireless Local Area Network (WLAN) based on OPNET simulator and evaluated the performance of the wireless local area network in a campus/university environment. Our model has been tested for two types of applications (PRINT and EMAIL) in two different sites each comprising of 20 users and found that among a set of other parameters Media Access Delay and Load were highly affected by the number of users per application with and without load balancing. Simulation performed shows the behavior of load balancing on wire-line and wireless network for both applications (print and email) [5-15].
