In a multi-point monitoring system where one receiver receives data from several tens of thousands of nodes, a multiple-access problem arises. Because a wireless sensor node cannot have much power, solving the problem by improving the receiver and not using power in the node is desirable, such as employing a carrier-sense operation. The developed receiver enables the reception of packets from 10000 nodes without carrier-sense operation at approximately 1% packet collision rate.本誌: 電気学会論文誌E（センサ・マイクロマシン部門誌） Vol.134 No.3 （2014） 特集：センサ・マイクロマシン英文特集号本誌掲載ページ: 72-73 p原稿種別: 研究開発レター／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejsmas/134/3/134_72/_article/-char/ja/ Show more
