Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Energy harvesting (EH) is a promising strategy to prolong the operation of energy-constrained wireless systems. Simultaneous wireless information and energy transfer (SWIET) is a potential EH technique which has recently drawn significant attention. By employing SWIET at relay nodes in wireless relay systems, the relay nodes can harvest energy and receive information from their source nodes simultaneously as radio signals can carry energy as ll as information at the same time, which solves the energy scarcity problem for wireless relay nodes. ,  study SWIET for nonregenerative orthogonal-frequency-division multiplexing (OFDM) amplify-and-forward systems in order to maximize the end-to-end achievable rate by optimizing resource allocation. Firstly,  propose an optimal energy-transfer por allocation policy which utilizes the diversity provided by OFDM modulation.  then validate that the ordered-signal-to-noise ratio (SNR) subcarrier pairing (SP) is the optimal SP scheme. After that,  investigate the information-transfer por allocation (IPA) and EH time optimization problem which is formulated as a non-convex optimization problem. By making the approximation at high SNR regime,  convert this non-convex optimization problem into a quasi-convex programming problem, where an algorithm is derived to jointly optimize the IPA and EH time. By analytical analysis,  validate that the proposed resource allocation scheme has much lor computational complexity than peer studies in the literature. Finally, simulation results verify the optimality of our proposed resource allocation scheme.
