Throughput Maximization for Wireless Powered Buffer‐Aided Successive Relaying Networks
Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 In this paper, we consider a wireless powered cooperative network, where two energy‐constrained buffer‐aided relays harvest energy from the source to assist the information delivery to the destination. To improve the spectral efficiency, a wireless powered successive relaying (WPSR) protocol is proposed to allow both relays to receive the information ...
