access icon free Operation strategy for wireless-powered heterogeneous sensor networks

A wireless-powered heterogeneous sensor network is considered whose sensor nodes (SNs) harvest energy from a radio signal emitted from a base node (BN) communicating with user nodes and then transmit the collected information to a data collection node. In order to maximise the throughput of the sensor network under the interference limit on the BNs, an algorithm that optimises the duration of the phases and the transmit power of the SNs is proposed. By comparing to a method with a fixed time ratio for energy harvesting, the benefit of the proposed method is verified.
