The channel coherence time in indoor WLANs normally exceeds multiple frame
transmission times. In light of this, we propose a new rate adaptation scheme, termed as the …

Rate adaptation is a mechanism unspecified by the 802.11 standards, yet critical to the
system performance by exploiting the multi-rate capability at the physical layer. I n this …

• If two consecutive ACK frames are not received correctly, the second retry and subsequent
transmissions are done at a lower rate and a timer is started.• When the number of …

One of the key challenges in designing a rate adaptation scheme for IEEE 802.11 wireless
LANs (WLANs) is to differentiate bit errors from link-layer collisions. Many recent rate …

Many rate adaptation algorithms have been proposed for IEEE 802.11 Wireless LAN
devices and most of them operate in an open-loop manner, ie, the transmitter adapts its …

Experimental studies have shown that traditional rate adaptation schemes for 802.11
wireless networks suffer from significant throughput degradation in highly congested …

Wireless technologies are being used in various applications for their ease of deployment
and inherent capabilities to support mobility. Most wireless standards supports multiple data …

Rate adaptation consists of using the optimal rate for a given channel quality: the poorer the
channel quality, the lower the rate should be. Multiple rate adaptation schemes were …

Rate adaptation is a common technique to exploit channel diversity in wireless networks.
Despite the many rate adaptation algorithms proposed for 802.11 networks, statistics-based …

Rate adaptation is a mechanism unspecified by the IEEE 802.11 standards, yet critical to the
system performance by exploiting the multirate capability at the physical layer. In this paper …
