Title:
CONTROL METHOD AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/023825
Kind Code:
A1
Abstract:
The present invention discloses a control method for controlling data return in a passive sensor network. The passive sensor network comprises an aggregation node and sensor nodes. The control method comprises following steps: controlling the aggregation node to spread energy to the entire passive sensor network; controlling the sensor nodes to collect the energy spread by the aggregation node; grouping, according to a predetermined clustering rule, the sensor nodes into clusters and selecting cluster heads; and controlling the sensor nodes of each cluster to transmit data to the corresponding cluster head and then to the aggregation node or the sensor nodes of a cluster closer to the aggregation node so as to eventually transmit the data to the aggregation node and closing the sensor node that completes data transmission. In addition, the present invention further discloses a control device. The control method and the control device of embodiments of the present invention enable each sensor node in the network to transmit useful data to the aggregation node with the highest probability by controlling the manner in which the sensor nodes return data.
