In this paper, we consider multi-hop wireless networks with decode-and-forward relays. Intermediate relays have no fixed power supplies and thus need to replenish energy via wireless energy harvesting from the source signal. The technique of simultaneous wireless information and power transfer (SWIPT) is utilized between every two adjacent nodes to transport both information and energy. Three general protocols of SWIPT are considered: power-splitting (PS), time-switching (TS), and hybrid which is a combination of PS and TS protocols. For each protocol, we formulate optimization problems to decide optimal PS and TS ratios so as to maximize end-to-end throughput under two schemes. Scheme 1 all..View full abstract
