Automatic IEEE 802.11 Rate Control for Streaming Applications

Overview Streaming multimedia content in real-time over a wireless link is a challenging task because of the rapid fluctuations in link conditions that can occur due to movement, interference, and so on. The popular IEEE 802.11 standard includes low-level tuning parameters like the transmission rate. Standard device drivers for today's wireless products are based on gathering statistics, and consequently, adapt rather slowly to changes in conditions. To meet the strict latency requirements of streaming applications, an advanced hybrid control algorithm are designed and implemented that uses Signal-strength (SNR) information to achieve fast responses. The paper reports on real-time experiments involving two laptops equipped with IEEE 802.11a wireless interface cards.
