要約(英語): This paper presents a novel receiver that simultaneously uses 50 channels to decrease the packet collision rate and can receive a packet without preamble; thus, the power consumption of a wireless sensor node during transmission can be reduced. 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.
