Abstract
Disclosed is a control method for controlling data return in a passive sensor network comprising an aggregation node and sensor nodes. The control method comprises the following steps: controlling the aggregation node to broadcast energy to the entire passive sensor network; controlling the sensor nodes to collect the energy broadcast by the aggregation node; clustering, according to a predetermined clustering rule, the sensor nodes and selecting cluster heads; and controlling each of the sensor nodes of each cluster to transmit data to a corresponding cluster head and then to the aggregation node or one of 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, a control device is also disclosed.
