Abstract
In this paper, we are observing scenario of unmanned aerial vehicle (UAV) data collection from sensor network, where each sensor harvests energy from the data-collecting UAV for its own information transmission. In first time instant, the wireless energy transfer (WET) to sensor nodes is performed, while in second time instant UAV collects data from sensor nodes. In order to take into account the possibility of occurrence of obstacles, that could block the line-of-sight (LOS) link in-between sensor nodes and UAV, and to in order to observe fluctuations of the LOS signal that are brought by shadowing effect, we have used the assumption of Rician Shadowed fading channels and analyzed the outage probability (OP) properties of such network. Closed form expression are derived for OP, and OP features are observed and discussed in the function of system parameters such are shadowing severity, targeted information rate, UAV location, and the time ratio of WET.
