“…In [7], the well-known "harvest-then-transmit" protocol was proposed, where the time allocated to the hybrid access point (H-AP) for downlink WET and the time and transmit power allocated to the sensors for uplink WIT were jointly optimized for system throughput maximization. Since then, related works have been extensively done in the context of WPSNs with relays [8], [9], full-duplex radio [10], [11], cognitive radio [12]- [15], MIMO [16]- [18] and nonorthogonal multiple access (NOMA) schemes [19]- [21]. However, the above works only focus on the spectrum efficiency of WPSNs, which may lead a great dissipation of energy during the downlink WET.…”

“…is emerging. Because of its intrinsic capability of self-sustainability, a lot of researches have been done on it; many of them focus on the high-efficient energy utilization [1][2][3]. As for this energy harvesting-wireless sensor networks (EH-WSN), the main challenge is to maximize its working performance under energy harvesting constraints, so studies on the MAC protocol, routing protocol, and cross layer optimization also obtain lots of achievements [4][5][6][7][8][9][10].…”
