In high mobility scenarios, the battery performance of wireless devices decreases due to an increase in power consumption, which occurrs from frequent handovers. therefore an energy efficient algorithm is suggested that chooses the optimal number of cooperative moving relays (MRs) from among several MRs deployed on the roof of the train in order to effectively use the transmit power n a NOMA based wireless network using HDAF MR and considering rayleigh fading environment.
