We propose a simple enhancement to the Distributed Coordination Function (DCF) of the IEEE 802.11 MAC protocol, called the Unified Multiple Access with Variable contention window (UMAV), to improve the throughput performance of the 802.11 DCF systems. The basic ideas of UMAV are that (1) a new P(polling)-mode is introduced for frame transmissions in addition to the conventional C(contention)-mode used in the DCF, so as to reduce the number of contending stations; and (2) an enhanced uniform… CONTINUE READING
