Abstract
Wireless Local Area Networks (WLANs) are becoming the de facto last hop technology. Since its inception, the expected reliability and bandwidth offered by a WLAN has dramatically increased. This is evident by examining a sample of applications that run today over residential and commercial-grade WLAN networks such as VoIP and P2P applications, the introduction of which is a strenuous addition to an already congested radio frequency spectrum.
In this work, we design and deploy a large scale WLAN in the OPNET Modeler simulation environment. We perform frequency assignment and AP placement to satisfy VoIP Quality of Service (QoS) requirements with respect to performance considerations and then follow a microcell deployment strategy to provide thicker coverage. After the simulation framework is built, we introduce pairs of P2P links and observe their impact on the performance of the overlaid network.
