摘要:The interest in cooperative relaying has boosted after the advent of simultaneous wireless information and power transmission (SWIPT) concept. Energy harvesting is seen as a promising candidate to solve the charging issue of small sensor networks that are not feasible to change periodically. We have considered two types of hardware for energy harvesting from radio frequency in this research time switching (TS) architecture and power splitting (PS) architecture. In our research, a cooperative relaying system of single intermediate node is assumed. The relay node is following amplify and forward protocol. Only destination node is harvesting energy and have focused on two issues for both TS and PS architectures (resulting four problem in total) one is to optimize the data rate while ensuring the power-harvesting rate achieved at destination higher than given threshold and other is optimizing power-harvesting rate at destination while ensuring the data rate is higher than given threshold. We have plotted the performance of all four problems for different scenarios.
