Description

In recent times wireless communication has become more popular with its commercial usage. WLAN has evolved over the years to facilitate wireless communications for commercial usage. IEEE 802.11 working group focuses on developing global standards that can support the WLAN evolution. There are many features that IEEE 802.11 working group emphases on to provide the best experience for the Wi-Fi user. The popularity of Wi-Fi among commercial users has demanded more importance in terms of traffic and congestion. IEEE 802.11 have come with many updates enhancing with additional spectrum space, method of spectrum utilization, and so on. There are a few aspects of Wi-Fi adoption that have been kept outside the scope of the 802.11 standards, which are open for research. Wi-Fi rate adaptation is one of newlinethe important aspects of research. Many researchers have contributed with effective newlinemethodologies to improve user experiences. The literature review proves the importance of rate adaptation in the performance of wireless communication. The different version of the IEEE 802.11 standard provides a set of transmission rates to choose from for single-stream transmission. It is important to switch the transmission rate dynamically for more efficient utilization of the physical medium in a fluctuating environment. Dynamically identifying the optimal transmission rate from a list of single-stream transmission rates is a tedious task. There are different causes for the change in channel conditions and packet loss in the network. Identifying the best data transfer rate for the next transmission is a tedious task in such a network. It requires identification of the exact cause of loss. Improper channel estimation may lead to the channel may be underutilized or overused. Both situations will degrade the newlineperformance of the network. Evaluating and identifying the latest channel condition is newlineimportant.
