Outline of Final Research Achievements

We have proposed a scheduling method called harvest-then-access, in which the access point supplies power energy to the terminals in the network at a constant interval, and the terminals transmit a data packet in a distributed manner. By adjusting the power supply interval appropriately, the network throughput is improved while terminal battery depletion is avoided, and the effectiveness of the proposed method has been confirmed. The appropriate power supply interval can be derived by establishing the mathematical model that considers the operation of the proposed scheduling based on the energy queuing model. The proposed scheduling's performance is confirmed to be higher than that of the conventional method. Finally, the mathematical model considers the characteristics of power supply with directional and omnidirectional antennas, and we have clarified the superiority of both schemes in terms of network throughput.
