To achieve the objective of minimizing the system transmit power consumption at required end-to-end rates
we propose the optimal energy-efficient relay selection and power allocation method for energy harvesting two-way relay network based on the power splitting-based relaying protocol when the system has perfect CSI and imperfect CSI
the optimal power allocation of two sources and optimal energy harvesting proportion at relays are formulated.Simulation results show that channel estimation error would increase the total transmit power consumption
and energy harvesting two-way relay network could achieve less power consumption compared to conventional two-way relay network.
