Wireless networks face a number of fundamental issues that do not arise in wired networks. The authors consider the sizing of network buffers in 802.11 based wireless networks. 802.11 is a set of standards for implementing Wireless Local Area Network (WLAN) computer communication using different frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). All internet routers contain buffers to hold packets during the time of congestion. Buffers are used to reduce the packet loss and to ensure high link efficiency. The widely used general rule-of-thumb is to have buffers size as the Bandwidth-Delay Product (BDP) of the network.
