In conventional RTS/CTS control, all the neighbor wireless nodes of a sender and a receiver wireless nodes are required to suspend their transissions of both control and data messages. Though collsions of messages are avoided due to the temporary suspension, fewer data messages are transmitted concurrently and the throughput of data messages in the wireless adhoc network is decreased. This paper proposes a novel method to realize higher concurrent data message transmissions based on the capture effects where one of the messages with higher receipt power with the predetermined margin is received among concurrently transmitted messages. That is, weaker restrictions for concurrent message transmissions based on the capture effects are induced and an extended RTS/CTS control protocol for the higher concurrent data message transmissions is designed. Here, based on the distance between neighbor wireless nodes, each wireless node determines settings of its own NAV by using two different kinds of NAVs.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告マルチメディア通信と分散処理（DPS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-05-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"2022-DPS-191"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":217948,"updated":"2025-01-19T15:19:40.866166+00:00","links":{},"created":"2025-01-19T01:18:22.292372+00:00"}
