The authors have previously proposed a dynamic load balancing method that can manage the status of the group of subscribers connected to the MQTT broker, and distribute messages based on the load status, in order to achieve message distribution in response to changes in the load on each subscribers. In this paper, we assume that messages are sent from numerous publishers with different time intervals and data sizes, and we have constructed an experimental environment using a public cloud service to evaluate its scalability. By comparing and evaluating the conventional static load balancing method and the dynamic load balancing method, we show that the dynamic load balancing method can also function effectively in large-scale IoT systems.","subitem_description_type":"Other","subitem_description_language":"en"}]},"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":"2025-02-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"32","bibliographicVolumeNumber":"2025-IOT-68"}]},"relation_version_is_last":true,"weko_creator_id":"80578"}}
