Buffers play a key role in 802.11/802.11e Wireless networks.802.11 is a set of standards for implementing Wireless Local Area Networks (WLAN) computer communication in the 2.4, 3.6 and 5 GHz frequency bands. They are created and maintained by IEEE LAN/MAN Standards Committee (IEEE 802).Buffers are used to accommodate short-term packet bursts so as to mitigate packet drops and to maintain high link efficiency. The use of fixed size buffers in 802.11networks inevitably leads to either undesirable channel underutilization or unnecessary high delays. The main objective of this paper is to maintain high network utilization while providing low queuing delays in 802.11 wireless networks through dynamic buffer sizing mechanism.
