Abstract	Incremental adaptive relaying has shown an attractive compromise between robustness and spectral efficiency in cooperative networks. Relays are used to incrementally assist sources to transmit data to their destinations. In this paper, a joint optimization of switching thresholds and transmit power assignments is proposed. The relaying is used, if either the signal strength at the destination is lower than a given threshold and at the relay is respectively and greater than another threshold. In the relaying phase, optimal transmit power assignment is considered at the source and at the relay. The proposed scheme permits to meet the best compromise among reliability, throughput and energy efficiency of cooperative source - relay - destination transmissions. We apply the proposed scheme to amplify and forward (AF) relaying systems. A selection of numerical results is illustrated for the performance analysis.
