摘要：
In this paper, optimal power control for source and relay in an energy harvesting relay network is studied. The relay network includes a source node, an amplify-and-forward relay node, and a destination node. The source and relay are able to harvest energy from nature, and have their own data to transmit. The source and relay adjust their transmission powers according to the amount of harvested energy and the data transmission requirement. The goal of power adaptation is to maximize the total throughput while satisfying the transmission power constraints of the source and relay, as well as the energy causality constraint. An optimization problem is formulated and its solution is obtained. Simulation results demonstrate the optimal transmission powers under various energy harvesting processes.
