The large scale use of Wireless Fidelity (Wi-Fi) technology in various fields has led to it rapid evolution. Deployed everywhere (at the office, in the coffee, at the airport, etc.), this technology has known a great success. Wi-Fi is the commercial denomination of the IEEE 802.11 standard. The Quality of Service (QoS) management within a multiple-traffic Wi-Fi MultiMedia (WMM) ad hoc network is a tedious task, since each traffic type requires a well determined QoS level. For this reason, the IEEE Working Group has proposed the IEEE 802.11e Enhanced Distributed Channel Access (EDCA) protocol at the MAC layer of WMM ad hoc networks.
