However, some RAW\u2019s slots may be overloaded; some RAW\u2019s slots may be lightly loaded or have no load because no stations (STA) allocated in these slots need to access channel. This work adopted (i) the Registered Backoff Time (RBT) mechanism such that each STA can register the backoff time for its future channel access in access point (AP) and (ii) the Claiming RAW mechanism such that STAs are allowed to notify AP that they have uplinked data to transmit. In this way, AP can (1) know which STAs have uplinked data to transmit and thus (2) re-schedule those STAs from the overloaded slots to the slots that (i) are underloaded or (ii) no STAs need to access channel based on STAs\u2019 RBTs in advance. As a result, the proposed Registration-based Regrouping for Load-Balance Channel Access (RRG-LBCA) method can achieve load balance among slots to increase the IEEE 802.11ah network\u2019s performance. The performance evaluation results shown that the proposed RRG-LBCA method can eliminate the collision situation and increase the aggregate throughput.<\/jats:p>","DOI":"10.1093\/comjnl\/bxad027","type":"journal-article","created":{"date-parts":[[2023,3,18]],"date-time":"2023-03-18T07:56:10Z","timestamp":1679126170000},"page":"884-898","source":"Crossref","is-referenced-by-count":0,"title":["Traffic-Aware Re-Grouping for Load Balance in IEEE 802.11ah IoT Network Based on the Registered Backoff Time Mechanism"],"prefix":"10.1093","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7195-4264","authenticated-orcid":false,"given":"Chung-Ming","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Computer Science and Information Engineering, National Cheng Kung University , No. 1 University Road, Eastern District, Tainan 70101 , Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7154-5951","authenticated-orcid":false,"given":"Shu-Hang","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, National Cheng Kung University , No. 1 University Road, Eastern District, Tainan 70101 , Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,3,17]]},"reference":[{"key":"2024041716572238200_ref1","first-page":"1","volume-title":"IEEE Standard for Information Technology--Telecommunications and Information Exchange Between Systems - Local and Metropolitan Area Networks--Specific Requirements - Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications Amendment 2: Sub 1 GHz License Exempt Operation.
