They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). Buffers play a key role in 802.11/802.11e wireless networks. Buffers are used to accommodate short-term packet bursts so as to mitigate packet drops and to maintain high link efficiency. Packets are queued if too many packets arrive in a sufficiently short interval of time during which a network device lacks the capacity to process all of them immediately. The use of fixed size buffers in 802.11 networks inevitably leads to either undesirable channel under-utilization or unnecessary high delays. In this paper our objective is to maintain high network utilization while providing low queuing delays in 802.11 wireless networks through dynamic buffer sizing algorithms.</p> <p class="IEEEHeading1" style="margin-left: 0in; text-indent: 0in; text-align: justify;"><strong><span style="color: #0d4c89;">References-</span></strong></p> <p style="text-align: justify;">[1] V.
