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.

Abstract: A resource allocation optimization method is provided for a Simultaneous Information and Energy Transfer (SIET) system. A baseband signal transmitted by a transmitting terminal of the system contain an information signal and an energy signals. The optimization method comprises a step P1 of determining a system pre-allocated parameter set, and solving steps for the step P1. The multicarrier broadband SIET optimization method disclosed is automatically configurable and feasible, giving consideration to both wireless energy supply and information transmission. The energy signal and the information signal are simultaneously and independently transmitted to the receiving terminal, therefore providing the energy required by the receiving terminal operating in a working mode. The method described can be widely applied into a variety of information and energy simultaneous transformation systems.
