—In this paper, an energy-efficient optimal relay
selection strategy which is jointly optimized with the energy-
efficient optimal power allocation solution for AF cooperative
transmission is proposed. The relay selection criterion is the
distance to the optimal relay locations where the minimum
transmission power of the source, the relay or their total
can be achieved. To determine those most energy-efficient
relay locations, a universal algorithm with low computational
complexity and easy implementation is also presented in this
paper. The simulations are conducted to validate our theoretical
analysis. The results show that with the relay selected by the
proposed strategy, the cooperative transmission can achieve
considerably high energy-efficiency.
