The study focused on achieving optimal resource allocation for Wireless Powered Communication Network (WPCN) using efficient energy management scheme. The proposed WPCN model was developed, structured with two Radio frequency channels viz-the RF energy transfer channel and the data communication. Analytical expressions were deduced to obtain optimal transmission power and system efficiency. Energy Management Scheme was applied in the system design to minimize the amplifier power consumption in

It ensures optimal consumption of the harvested energy for continuous operation by the sensor node. A testbed was developed to measure the parameters and the system model characteristics which facilitates adequate evaluation of the energy management scheme. The results obtained showed that the proposed scheme adaptively controls the WPCN for optimal energy neutrality and high-efficiency RF power transfer. The proposed energy management scheme was observed to consume less than 50% of the power consumed by the no amplifier duty cycling scheme.
