Today, most Wireless LANs (W LAN) are connected to the backbone via a wired Distribution System (DS). A Wireless Distribution System (WDS) provides quick and easy networking in circumstances that require temporary network services or when cabling is difficult, for example, in open area conversations, disasters and military usages. WDS can be used to extend the range of wireless service coverage. Transmitting Voice-over-IP (VoIP) traffic over WDS to a WLAN in the straightforward way may fail to fulfill the tight delay requirement, and may severely limit the system capacity. This paper extends the M-M scheme for WLAN connected via a WDS.
