description The invention discloses an energy-saving relay selection method for a wireless energy collection cooperative communication system, which correspondingly adopts a single-relay forwarding strategy and amulti-relay forwarding strategy under the condition that the energy of a relay node with an EH capability meets the forwarding requirement and does not meet the forwarding requirement. When the energy of part of the relay nodes meets the forwarding requirement, an optimal relay node can be selected from the relay nodes to forward a signal at the optimal power; And when the energy of all the relaynodes does not meet the forwarding requirement, forwarding by using the plurality of relay nodes in a cooperative manner, and carrying out signal combination at a receiving end. No matter a single relay forwarding mode or a multi-relay forwarding mode is adopted, energy can be saved as much as possible while effective signal transmission can be guaranteed, utilization of collected energy is optimized, and system performan
