    Abstract: 綠能通訊目的為珍惜有限資源,在能量的使用效益與排程來最佳分配,對於未來資源有限下有很大的幫助,不同於先前研究大部分沒有考慮能量限制與隨機性的問題,本研究由能量採集不確定性的角度中,探討綠能通訊對於能量的控管,以及最佳化排程帶來的效能。
    在本篇論文中,吾人探討應用於線上情況(online case)與離線情況(offline case)之綠能中繼系統;在線上情況利用馬可夫決策過程(Markov decision process, MDP)來找出系統在不同狀態下的最佳決策,在離線情況下利用最佳化形式來解決,並提出一簡化複雜度之次佳解。
    ;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.
