The QoS in wireless ad-hoc networks as defined by the standard IEEE802.11e (EDCA): functions so as to guarantee the high priority traffic (i.e. Multimedia and Real-time traffics). The QoS is managed in each station by differentiating the packets into categories depending on their priorities. These packets will access the channel with varying waiting times. However, EDCA cannot control traffic when there is a congestion to guarantee the QoS required by real-time and multimedia applications, specially when the problem of the hidden nodes exists. Thereby, the ill-behaved sources consume the majority of the available bandwidth. This leads some of the source nodes (i.e. Out of range nodes) to suffer from the lack of bandwidth and unfairness. So, without a proper control mechanism, this leads to degrading the QoS guarantees. To address this issue, we have proposed (FQ-EDCA): a Fairness Queuing model for EDCA. This paper aims to evaluate the scalability of FQ-EDCA and its network performance to have more end-to-end QoS guarantees.
