However, because it is affected by bandwidth limitations and contention control specific to the sub-1 GHz band, as well as transmission-time restrictions imposed by national regulations, it is important to understand upper-layer performance in TCP/IP communications. The effects of TCP congestion control algorithms and maximum send/receive buffer sizes on communication performance in an IEEE 802.11ah environment were experimentally evaluated using CUBIC, Reno, and BBR. The results showed that CUBIC and Reno improved throughput as the buffer size increased, while exhibiting a significant increase in RTT. In contrast, BBR maintained a low RTT, but its throughput improvement was limited. These results suggest that application-aware selection of TCP settings is essential in IEEE 802.11ah environments.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2026-05-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"18","bibliographicVolumeNumber":"2026-IOT-73"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"created":"2026-05-14T07:17:19.669530+00:00","updated":"2026-05-14T07:17:24.003140+00:00"}
