“…In addition, Das et al [20] evaluate IEEE 802.11 WLAN frame aggregation under different network conditions, Hajlaoui et al [21] applied two-dimensional Markov chain model, and Lee and Hwang [22] suggested A-MPDU aggregation with an optimal number of MPDUs for delay requirements. Moreover, Akpanobong et al [23] extend the throughput performance of low SNR scenarios using the two-level frames aggregation with enhanced A-MSDU.…”

“…In view of the fact that frame aggregation techniques have improved network performance, they do so at the expense of more overhead. Therefore, a novel approach is needed to boost A-MPDU performance, by extending Akpanobong et al [23]. As a result, this work develops an improved A-MPDU technique and efficient two-level aggregation to boost the throughput and efficiency of the classic A-MPDU.…”

<p>One of the most important frame aggregation features for enhancing the speed of IEEE 802.11n wireless local area networks (WLANs) through sharing headers and timing overheads is an aggregate MAC protocol data unit (A-MPDU). However, because aggregation overhead affects A-MPDU frame size, the A-MPDU performance falls short of user expectations. The variable signal-to-noise ratio (SNR) is significantly decreased as a result of the influence of lost sub-frame on the volume of sub-frames that may be aggregated (the level of aggregation). In order to solve this issue, this study suggests an improved A-MPDU with reduced header overheads as well as a efficient two-level aggregation technique based on enhanced A-MPDU. To test the suggested plan, a simulation experiment was run on NS-3. The results show that the suggested two-level aggregation approach works better than the existing methods by achieving higher throughput, SNR, and a efficient medium access control (MAC) layer.</p>
