sensing causes huge network traffic in spatiotemporally dense areas where participants upload large numbers of sensor values. Furthermore, sensor values of participatory sensing are often inaccurate due to both measurement error and variations in the sensing accuracy of devices. Thus, if we control the network traffic regardless of the accuracy of sensor values, the measurement results will be unreliable. We propose a method to control a sampling rate of devices while maintaining high reliability of the measurement results. This method involves calculating a sufficient number of sensor values to estimate the true value on the basis of the confidence interval for a population mean of sensor values from a spatiotemporal area. The same sampling rate is then set for all sensing devices in the area based on that amount, and network traffic is reduced. Empirical evaluations show that our method is less affected by inaccurate sensor values than a conventional method that also samples devices in order to reduce network traffic. Moreover, our method reduces the network traffic to one ninth that required by another conventional method that maintains a fixed sampling rate under the condition that the confidence interval for the population mean of sensor values is below a given threshold.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2202","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2190","bibliographicIssueDates":{"bibliographicIssueDate":"2014-09-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"55"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":103118,"links":{}}
