Abstract

Rate adaptation algorithms play a vital role in maintaining a high level of performance and reliable data transmission in wireless local area networks (WLANs) by determining the transmission rate for data packets. Using two mobility models and considering three propagation loss methods, this paper seeks to evaluate the performance of rate adaptation algorithms in WLANs by comparing four different rate adaptation algorithms utilizing the NS3 network simulator, which includes basic as well as advanced methods incorporating Signal to Noise Ratio (SNR) and Received Signal Strength Indicator (RSSI). Considering the mean values of throughput rates, delay times and packet losses , it is safe to say that based on received signals' strengths' indications along with ratio information; adapting its own transmission speed seems to be relatively more efficient. The examination conducted in this analysis helps expand our understanding on how different conditions such as mobility and propagation loss can impact rate adaptation algorithms' efficacy in WLANs, but on the other hand there are some issues unresolved such as taking into account additional parameters and various possible scenarios as well as dealing with the pitfalls of simulation-based approaches. In any case, this study lays down the groundwork for upcoming studies regarding rate adaptation methods implemented within wireless local area networks, and by implementing these findings one can improve both design and operational aspects of WLANs across a range of scenarios.
