Abstract
In this paper, an effective relay node (RN) selection scheme based on optimal power splitting ratio (PSR) in dual hop decode and forward (DF) cooperative relay network (CRN) under the SWIPT framework is proposed. A single antenna multiple intermediate energy harvesting (EH) RNs network between source and destination is considered, where multiple EH RNs harvest energy from radio frequency (RF) signal transmitted by the source node (SN). Each EH DF RN uses a power splitting (PS) protocol to represent the rate-energy (RE) exchange between the energy used to decode the RN information signal and the rest of the energy collected to transmit the decoded signal to the destination node (DN). In this paper, we have computed the theoretical as well as the simulated results in terms of energy harvesting at the RNs, optimization of end-to-end data rate with an efficient RN selection scheme based on optimized PSR and compared with conventional PSR relay selection scheme. Furthermore, based on the proposed scheme we have derived the expression of outage probability and showed the performance in terms of energy conversion efficiency and signal to noise ratio (SNR) at different threshold rata rates. We have shown that our proposed scheme performs better than conventional equal PSR scheme.
