M. Tech. Electrical Engineering. / In a Wireless Local Area Network (WLAN), as the signal travels from the transmitter to the receiver, it experiences various forms of impairments that cause fading and path loss. To cater for this problem, monitoring the link between the transmitter and receiver becomes imperative. This study focuses on the design of a link adaptation algorithm that seeks to improve the quality of service delivery in IEEE 802.11n networks. From the results, it is shown that the Greedy Algorithm (GA) performed far better than that of Auto-Rate-Fallback (ARF) and it is also shown that the Optimal Algorithm (OA) approach outperformed GA and ARF in terms of throughput and efficiency. Simulations results of both proposed algorithms proved to be more efficient than the existing ARF algorithm. Thus, it is shown that the proposed algorithms have the potential of enhancing the quality of service in IEEE 802.11n network.
