To exchange as much data as possible in short intervals for connecting vehicles passing each other, it is essential to improve the success rate of reception. In this paper, we propose a method to realize high-level throughput which can be implemented on application layer without upgrading the existing MAC layer protocol. Although this method works on CSMA/CA, it can realize an efficient slot allocation mechanism similar to that of TDMA. This method was evaluated by simulation using actual traffic data. The results of the simulation show that our method realizes effective throughput stably in spite of rapid change in vehicle density.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"130","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"116","bibliographicIssueDates":{"bibliographicIssueDate":"2010-01-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"51"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":67570,"links":{}}
