A novel model to eliminate the doubly near‐far problem in wireless powered communication network
IET Communications, Volume 15, Issue 12, Page 1539-1547, July 2021., 2021 Abstract In this paper, the newly emerging wireless powered communication network is studied. In doing so, the performance of the global controller (GC) is evaluated, which coordinates the wireless energy transmissions between two sensor nodes. Both the sensors have the same harvested energy for uplink (UL) transmission of information through time ...
