Abstract

We consider a distributed power-beacon (PB)- assisted wireless powered communication network that consists of multiple PBs, multiple transmitters, and one receiver. The transmitters harvest energy from the PBs, and then transmit their individual data to the receiver via time division multiple access. Fading coefficients of channels between nodes are assumed independent but not necessarily identically distributed Nakagamim random variables. We derive an exact expression for the achievable throughput. A closed-form approximated expression of the throughput in the high signal-to-noise ratio regime is obtained. Moreover, we proposed the optimal time allocation method to maximizing the sum throughput of the whole system. Our analysis is corroborated by Monte Carlo simulations.
