Wireless local area networks (known as Wi-Fi) are widely used as an extension to the Gigabit Ethernet backbone network for ubiquitous user access to network services from various office buildings, lecture theatres, and libraries within the Campus. While the performance of Gigabit Ethernet infrastructure as well as Wi-Fi networks has been studied and reported extensively in the network literature, the impact of increasing wireless video clients (nodes) on system performance has not been fully explored yet. In this paper, we investigate the effect of increasing wireless nodes on the performance of video streaming over a campus Gigabit Ethernet backbone infrastructure. We develop a simulation model (using OMNET++) and measure the quality-of-service parameters, such as end-to-end delay, throughput, and packet loss for various network scenarios and configurations. Simulation results show that the increasing wireless video clients in the subnets have significant system performance drawbacks (i.e., reduce throughputs up to 93% and increase end-to-end delays up to 99%). The findings reported in this paper provide some insights into the design and deployment of next-generation Wi-Fi networks for Internet access.
