Wireless network sub-channel power distribution method based on wireless energy collection

Abstract

The invention discloses a wireless network sub-channel power distribution method based on wireless energy collection. The method comprises the following steps: continuously iterating to determine minimum energy required by an energy collection user in a current time slot; continuously iterating to determine the transmitting power allocated to the cooperative user transmitter on the selected sub-channel in the first sub-time slot, and further calculating the energy collected by the energy collection user transmitter in the current time slot; when the sum of the obtained energy and the residualenergy of the previous time slot is not less than the required minimum energy, continuously iterating to determine the transmitting power allocated to the cooperative user transmitter on the selectedsub-channel in the second sub-time slot; continuously iterating to determine the transmitting power allocated to the energy harvesting user transmitter on the selected sub-channel in the second sub-time slot, and further calculating the actual throughput of the energy harvesting user in the current time slot; and when the actual throughput is not smaller than the minimum throughput, completing thedistribution of the transmitting power. The method has the advantages of low calculation complexity and high energy utilization rate.
