To quantify the power consumption and the task execution delay, an experimental evaluation run various services on a wireless sensor node. The evaluation result shows that it is difficult to reduce power consumption and task execution delay at the same time because there is a trade-off between them. Additionally, to validate feasibility of the multicore sensor node, the task flow analysis on software in wireless sensor networks is conducted. The analysis result shows that we can estimate a number of required cores to implement the software on a multicore sensor node.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告ユビキタスコンピューティングシステム（UBI）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2009-07-09","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2009-UBI-23"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":62687,"updated":"2025-01-22T02:30:15.631581+00:00","links":{},"created":"2025-01-18T23:24:35.728395+00:00"}
