This paper presents the analysis of the scenario where a relay node is used to enable communication between a source and an Internet of Things (IoT) edge node. The position of the relay is set to provide line-of-sight communication between the source and the relay node while communication in the relay-IoT edge link is still jeopardized by obstacles. As the relay node is energy limited, it is powered by RF energy from the source based on a time-switching protocol. Assuming that the energy harvester is a nonlinear device, the impact of nonlinearity, channel and system parameters on outage system performance is investigated and discussed.
