- In this paper, a spectral and energy efficient-path selection scheme is proposed to enhance downlink system throughput and reduce transmission energy consumption in two-hop cellular systems. In the proposed scheme a base station (BS) determines either a single-hop or two-hop path that uses less resource. The simulation results show that the proposed scheme outperforms a conventional path selection scheme which uses high Signal to Interference and Noise Ratio (SINR) strength based path selection in terms of system throughput and energy consumption and provides an insight into choosing the appropriate RS position and optimal frequency reuse factor. © 2011 Springer-Verlag.
