## Abstract

In this work we are particularly focused on the characterization of the RF power received by each harvester and

its impact in terms of the probability of accumulating enough energy to transmit a packet. The multiple nodes

forming a Radio Frequency (RF) Energy Harvesting Network (RF-EHN) have the capability of converting

received electromagnetic RF signals in energy that can be used to power a network device (the energy

harvester). Traditionally the RF signals are provided by high power transmitters (e.g., base stations) operating in

the neighborhood of the harvesters. Recently, RF energy harvesting has attracted much attention and many

efforts are being dedicated to develop innovative RF energy harvesting technologies as well as to investigate the

performance of the networks formed by the harvesting devices. Admitting that the transmitters are spatially

distributed according to a spatial Poisson process, we start by characterizing the distribution of the RF power

received by an energy harvester node. Considering Gamma shadowing and Rayleigh fading, we show that the

received RF power can be approximated by the sum of multiple Gamma distributions with different scale and

shape parameters. Using the distribution of the received RF power, we derive the probability of a node having

enough energy to transmit a packet after a given amount of charging time. The RF power distribution and the

probability of a harvester having enough energy to transmit a packet are validated through simulation. The

numerical results obtained with the proposed analysis are close to the ones obtained through simulation, which

confirms the accuracy of the proposed analysis.
