Abstract
A system for downlink transmission using heterogeneous power includes a plurality of sensor nodes, a coordinator connected to a network including the plurality of sensor nodes and configured to transmit data to the plurality of sensor nodes, a power source configured to supply power required for the coordinator to transmit data to each of the plurality of sensor nodes through a single transmission passage at a position away by a specific distance from the network, to the coordinator, and a battery configured to supply power required for the plurality of sensor nodes to perform communication within the network, to the plurality of sensor nodes, wherein when a destination node as a reception target of the data, among the plurality of sensor nodes, receives the data, the destination node transmits a signal indicating the data reception to the other remaining nodes among the plurality of sensor nodes.
