Abstract: In energy harvesting communications, user transmits messages using energy harvested from nature during the course of communication. In energy harvesting introduced the energy cooperation, where the user wirelessly transmits a portion of its energy to another energy harvesting user. where the transmitter sends one signal and receiver receives the received signal into two parts by either power splitting or time switching by using SWIPT (simultaneous wireless information power transmit). The energy cooperation save-then transmit (EC-ST) scheme is employed consider additive white Gaussian noise one-way channels with twoway energy transfer under a deterministic energy arrival rate. In this case, the optimal active ratio and the energy cooperation power are obtained in closed form to achieve the maximum throughput. Next, for Rayleigh block fading channels with a stochastic energy arrival rate, the optimal energy cooperation power for minimizing the outage probability. This paper concentrates on the optimal performance of the P2P wireless communications within T seconds. To begin with, the (EC-ST) scheme to additive white Gaussian noise (AWGN) one-way channels with two way energy transfer under a deterministic energy arrival rate.
