Abstract :
In this paper, we study an energy-efficiency relay-based protocol that can select a proper PHY mode and a transmission power level, and analyze its energy-efficiency, defined as the number of data bits transmitted per unit energy. Evaluation results show that this protocol and its degraded version can provide significant improvements on the energy-efficiency and remarkably enhance the overall system performance.
