In all select relay selection protocol using decode and forward (DF) relaying techniques, the source transmits data to every relay that is currently connected to the network. Only relays that successfully decode the data they receive will forward it to the intended destination after completing the necessary signal processing. As a result, the network no longer incorporates those source to relay links that did not receive the signal correctly. In addition, all the energy that was put into these connection is now wasted. In light of this, in this paper, I propose the concept of limited feedback (from relay to source) to determine the transmitted power of each source to relay (S-R) connection, ensuring that all links continue to function and contribute to data transmission. This brief feedback consists of a few bits that provide the relay identification and the instantaneous power requirement.
