In WMNs, due to using wireless medium, communication quality of links significantly changes as time passes. To overcome this fluctuation, several dynamic link metrics have been proposed that represent the quality of links as link metrics so that the shortest paths avoid low-quality links. However, because link metrics are designed to follow relatively slow metric changes, it is not sufficient for real network to supply stable communications. In this study, we propose a method that builds a WMN in multichannel environment and switches the forwarding links dynamically in case of congestion to improve throughput and stability of communications. We evaluate the proposed method through simulation experiments.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告マルチメディア通信と分散処理（DPS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-05-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"15","bibliographicVolumeNumber":"2012-DPS-151"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:36:15.909715+00:00","id":82358,"links":{}}
