Abstract :
This paper compares the theoretical and the experimental throughput of an 802.11 adhoc network implementing quality of service (QoS) mechanisms. The theoretical model provides the throughput of each access category (AC) of each node in saturated and non-saturated traffic conditions. The experimental setup is described in detail to enable the reproduction of the presented measurements. This setup adopts the widely used multiband atheros driver for wireless fidelity (MADWiFi), which, however, provides the QoS option for centralized operations only. Hence, this study describes the adjustments to the MADWiFi source code that guarantee the control of the QoS parameters in adhoc mode.
