Abstract

This paper presents an analysis for the Age of Information (AoI) in a wireless sensor network consisting of multiple VLC/RF IoT sensors. In this network, we use an energy harvesting method, and all sensors utilize the stored energy in their batteries and transmit update packets with a specific power. We present two main optimization problems based on PD-NOMA scheme for average AoI with the sensor’s transmit power constraint. By optimizing these problems, the average AoI for each sensor and the total average AoI in the proposed system are reduced by 10% and 15%, respectively.
