摘要: Inspired by the green communication trend of next-generation wireless networks, we present an opportunistic energy-efficient cooperative method. Different from classical relaying selection schemes, which adopt either end-to-end signal-to-noise ratio or capacity as metrics, our scheme uses energy efficiency metric for selecting best relay resorting to direct transmission. Simulation results demonstrate significant savings achieved when compared with decode-and-forward based on capacity. In addition that, dynamic time allocation and increasing number participating relays are shown have a notable effect efficiency.
