“…Consequently, this paper presents an analytical model to examine overhead and throughput under saturation conditions (S). The overhead model is based on the work of Noma et al [9], whereas the extension model of normalized distributed coordination functions (DCF) throughput in saturated channel situation to frame aggregation is based on the study of Bianchi [25].…”

“…The work by Qian et al [8] highlighted that, two-level aggregation is created by combining A-MSDU and A-MPDU. However, the performance of frame aggregation methods suffered severely in an erroneous channel, which can lead to the emergence of unexpected problems such as corruption aggregation frames [9]- [12]. Certain improvements to the traditional frame aggregation method are suggested as a result of these challenges.…”

<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>

“…However, in a specific scene, the two-level aggregation may bring serious retransmission overhead. 17,18 Besides, in the A-MPDU aggregation mode, the SNR (signal-to-noise ratio) and FER (frame error rate) will also affect the frame aggregation efficiency. 19 Jan and Sebastian 20 discussed the optimal MPDU size in different channels under the latest IEEE 802.11ax protocol.…”

“…Meanwhile, two aggregation types can be combined with each other to form a third aggregation type: two‐level aggregation, which can perform A‐MPDU aggregation by using A‐MSDU as a single MPDU to improve the MAC layer frame transmission efficiency. However, in a specific scene, the two‐level aggregation may bring serious retransmission overhead 17,18 . Besides, in the A‐MPDU aggregation mode, the SNR (signal‐to‐noise ratio) and FER (frame error rate) will also affect the frame aggregation efficiency 19 .…”

The Linear Wireless Ad-Hoc Network (Linear WANET), as a branch of the Ad-Hoc network, refers to a self-organizing multi-hop wireless network in which nodes are arranged linearly. Frame aggregation and RTS/CTS schemes are introduced in IEEE 802.11 aims to improve network transmission performance. However, the traditional mechanisms may not have good adaptability in linear multi-hop networks. Thus, we defined a Linear WANET simulation model based on the IEEE 802.11 protocol. We established this model on the NS-3 network simulator to perform A-MSDU, A-MPDU, and two-level frame aggregation simulation and analyzed the aggregation performance under different channel environments. Meanwhile, the RTS/CTS and TXOP mechanisms were also simulated in this article. We analyzed the performance of each mechanism in a Linear WANET under saturated and unsaturated environments. We found that the linear multi-hop characteristic has a significant impact on the performance of the frame aggregation mechanism. In the Linear WANET, the A-MSDU mechanism can improve system performance to a limited extent, but at the same time, it will increase the packet loss rate and delay. So, the two-level aggregation can improve the maximum throughput of the system with better channel conditions. In the case of single A-MPDU aggregation, there has a lowest data delivery interval that the Linear WANET system can withstand. The A-MPDU mechanism is a better choice for the poor channel conditions with unsaturated system throughput. Meanwhile, we also found that the native TXOP mechanism cannot effectively improve the system efficiency of Linear WANET. The RTS/CTS mechanism can enhance system throughput performance in most cases, especially in a saturated throughput environment.
