Relay links are expected to play a critical role in the design of wireless networks. In this paper, we investigate the energy efficiency of relay communications under two different scenarios: when the relay has unlimited and when it has limited power supply. Relative merits of these relay schemes in comparison with direct transmissions are discussed.
