Abstract
We examine the age of information (AoI) in a status update system that incorporates energy harvesting and the slotted ALOHA protocol. We derive analytically the average AoI and the probability that the AoI exceeds a given threshold. Via numerical results, we investigate the trade-off between i) transmitting a new update whenever possible, and ii) transmitting only when sufficient energy is available to increase the chance of successful delivery. The two strategies turn out to be beneficial for low and high update generation rates, respectively. However, an optimized approach that balances the two strategies outperforms them significantly in terms of both AoI and throughput.
