Optimization of Threshold based Rate Adaptation Technique in Wireless Network
Adaptive modulation and coding technique has emerged as a bandwidth efficient transmission scheme. It is motivated by its ability to improve spectral efficiency by adapting the transmission rates to the variations in channel signal-to-noise ratio. The implementation of apt rate adaptation algorithms based on either signal to noise ratio or successful packet transmission has been the crucial factor in adaptive modulation and coding. This paper focuses upon enhancing the data rate while implementing adaptive modulation and coding by modifying the rate adaptation algorithm in the context of IEEE 802.11 WLAN.
