Enterprise WLAN uses an IEEE 802.11 wireless channel to transfer data from a variety of network applications. The predominant types of traffic are the various types of real-time traffic that currently play an important role in business operations. Network applications with real-time traffic have different network requirements: packet bandwidth, jitter, packet delay, and loss tolerance. WLANs have variable packet throughput depending on the bandwidth, the number of connected wireless stations, the traffic intensity of the network applications, and completely different media access protocols. Real-time traffic creates challenges and demands on wireless resource management. The purpose of this paper is to improve end-user experience of real-time traffic transmission through the wireless channel. To achieve this goal, we developed a testbed to obtain the mean and variance of wireless channel service time using event-driven simulator. We also proposed an analytical model of enterprise WLAN and equations to compute the guaranteed traffic intensity through wireless channel. An example showing how to obtain the guaranteed traffic intensity using the analytical model and event-driven simulation results is provided. |
