Consequently, it is feasible to adjust the frame size to maximize the system throughput. The existing adaptive aggregation solutions do not consider the effects of different traffic scenarios and they use a Poison traffic model which is inadequate to represent the real network traffic scenarios, thus leading to suboptimal solutions. In this study, we propose some adaptive aggregation strategies which employ a novel dynamic adaptive aggregation policy selection algorithm in addressing the challenges of heterogenous traffic demand in the downlink MU-MIMO channel. Different traffic models are proposed to emulate real world traffic scenarios in the network and to analyze the proposed aggregation polices with respect to various traffic models. Finally, through simulation, we demonstrate the performance of our adaptive algorithm over the baseline FIFO aggregation approach in terms of system throughput performance and channel utilization in achieving the optimal frame size of the system.<\/jats:p>","DOI":"10.12720\/jcm.16.8.311-322","type":"journal-article","created":{"date-parts":[[2021,10,20]],"date-time":"2021-10-20T07:51:00Z","timestamp":1634716260000},"page":"311-322","source":"Crossref","is-referenced-by-count":8,"title":["A New Adaptive Frame Aggregation Method for Downlink WLAN MU-MIMO Channels"],"prefix":"10.12720","author":[{"name":"School of Information and Software Engineering, University of Electronic Science and Technology China (UESTC), Chengdu, 610054, China","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lemlem","family":"Kassa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Davis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingye","family":"Cai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianhua","family":"Deng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4977","published-online":{"date-parts":[[2021]]},"reference":[{"key":"ref0","unstructured":"[1] Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications; Amendment 6: Enhancements for High Efficiency WLAN, IEEE P802.11ax Draft 3.0, 2018."},{"key":"ref1","doi-asserted-by":"publisher","unstructured":"[2] O.
