本文研究了正交频分多址中继系统的能量有效资源分配,该系统由传统的公用电网和一个可再生能源发电机配备了存储设备。无线电资源的最佳利用取决于可再生能源发电和移动的业务的特性,这表现出时间和空间的差异。该方法利用李雅普诺夫优化方法将问题分解为联合流量控制、无线资源分配和能量管理三个部分,而不需要系统统计的先验知识。实验证明,该算法在数据缓冲区和存储设备容量有限的情况下,可以获得接近最优的性能。仿真结果表明,该算法能够在系统效用和常规能耗之间实现灵活的折衷。与其他方案相比,该算法具有更好的性能。
This paper investigates the energy-efficient resource allocation for orthogonal frequency-division multiple-access relay systems, where the system is supplied by the conventional utility grid and a renewable energy generator equipped with a storage device. The optimal usage of radio resource depends on the characteristics of the renewable energy generation and the mobile traffic, which exhibit both temporal and spatial diversities. The Lyapunov optimization method is used to decompose the problem into the joint flow control, radio resource allocation, and energy management without knowing a priori knowledge of system statistics. It is proven that the proposed algorithm can result in close-to-optimal performance with capacity-limited data buffer and storage device. Simulation results show that the flexible tradeoff between the system utility and the conventional energy consumption can be achieved. Compared with other schemes, the proposed algorithm demonstrates better performance.
