A battery is usually used for driving these sensor node. However, this is problematic in that dead battery replacement is then required for a huge number of nodes. To tackle this problem, we are researching on battery-less wireless sensor network system called \"Solar Biscuit\" which employs a solar cell for its energy source. Because energy obtained from energy-harvesting device tends to be unstable depending on environment change (e.g. climate change), the key challenge in designing battery-less WSN is how to ensure long-term stable operation of the network. To enable such stable operation, we believe that power consumption in multi-hop communication should be reduced drastically as the first step. From this point of view, we are trying to utilize radio-controlled clock technology to develop a practical low-power multi-hop communication scheme for battely-less WNSs. This paper introduces design of a radio-controlled clock based scheduled communication mechanism as well as its implementation and initial experimental results.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"118","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告モバイルコンピューティングとユビキタス通信（MBL）"}],"bibliographicPageStart":"113","bibliographicIssueDates":{"bibliographicIssueDate":"2007-05-18","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"44(2007-MBL-041)","bibliographicVolumeNumber":"2007"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
