Short Packet Communications in Large-Scale Wireless Powered Networks

Abstract

Wireless power transfer and short packet communications are two technologies ideal for next-generation lowpower wireless networks such as the Internet of Things. In this paper, we consider the employment of wireless powered short packet communications and investigate its performance from a macroscopic point-of-view. Specifically, we consider a terminal randomly deployed in a single-cell, which communicates with the cell's access point (AP) over finite block-lengths. The terminal uses the energy harvested from the AP's transmitted signals to transmit back to the AP the required information bits. We derive analytical closed-form expressions for the average error probability and delay, in terms of the terminal's possible locations in the cell. Our results provide important insights behind the performance of wireless powered short packet communications in large-scale networks.
