Abstract

This paper studies age of information minimization for a large network, where transmitters harvest energy from power beacons and send time-sensitive updates to receivers. The distributions of power beacons and energy harvesting nodes are considered to be homogeneous Poisson point and binomial point processes, respectively. We focus on probabilistic update policies for energy harvesting nodes and derive a closed-form expression for the average age of information of a node in the network utilizing stochastic geometry. Specifically, the age of information minimization is formulated as a stochastic optimization problem, transformed to a convex program and solved by the projected gradient descent algorithm.
