Abstract

The data-oriented approach was initially proposed towards novel transmission strategies for individual data-transmission sessions by considering instantaneous operating conditions. Aligned with this, the present contribution focuses on the analysis of the delay outage ratio (DOR), a data-oriented performance metric, when far-field wireless power transfer is utilized with network elements capable of energy harvesting from ambient RF signals prior to the transmission periods. To that end, simple and accurate analytic expressions are derived considering the involved battery charging intervals as well as the length of the data segment, available bandwidth and delay constraints. These expressions are corroborated by numerical simulations and they are subsequently used in developing useful theoretical and practical insights of interest. Besides highlighting the importance of the new data-oriented DOR metric, the offered results are shown to be useful in the design of realistic energy harvesting-based data transmission systems in future networks.
