802.15.4ネットワークでは，メディアアクセス制御の方式として従来のCSMA-CAに加え2024年版よりオプションとして，Suspendable CSMA-CAが標準化されている．従来のCSMA-CAは，通信路が混雑している状況下ではバックオフの再試行が頻発し，バックオフ試行回数が上限に到達することでパケット送信を諦め，パケット到達率（Packet Delivery Rate: PDR）が低下するという課題がある．このような課題を解決するために，Suspendable CSMA-CAが標準化された．しかし，Suspendable CSMA-CAはPDRを向上させる一方で，周辺機器の送信が終了するまでバックオフを一時停止するため，スループットが低下するという課題がある．本稿では，この課題に対処するために，Suspendable CSMA-CAにおけるCCA手法（Carrier Sense: CSおよびEnergy Detection: ED）を状況に応じてスロットごとに切り替える手法を検討し，同手法のスループットへの影響について議論する．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告モバイルコンピューティングと新社会システム（MBL）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2025-11-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"18","bibliographicVolumeNumber":"2025-MBL-117"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"created":"2025-11-13T07:02:51.799055+00:00","updated":"2025-11-13T07:46:18.879243+00:00"}
