| Summary: | 碩士 === 國立中央大學 === 通訊工程學系 === 103 === Toward a green communication, the scheduling and the optimal power allocation are two key approaches to address the problem of inadequate resources in the future wireless communications. The existing schemes are based on fixed and stochastic energy and they didn’t take the energy causality constraints into account. In this work, we focus on the optimal power control schemes under the uncertainty of harvested energy, and we also consider both half-duplex and full-duplex protocols to transmit the data. In this research, we consider online case and offline case with an energy harvesting (EH) sources communicates with the destination via an EH decode-and-forward relay. In online case, we formulate the problem as a Markov decision process to find the best policies. In the offline case, we use optimal form to solve the problem and propose a suboptimal simplifying the complexity. The main contribution of this research is to find the optimal policies that maximize the throughput and minimize the outage probability under different situations.
