The majority of wireless local area network (WLAN) technologies, including the wireless fidelity (WiFi) [1] standard IEEE 802.11 [2], is characterized by the use of a single shared channel. The use of a single channel is very different from most wireless cellular technologies [for example, Global System for Mobile communications (GSM)], where communications simultaneously occur in independent wireless channels deployed in different time slots and frequency bands. Indeed, the use of a shared channel necessitates the specification of some access
