Average Peak Age of Information Analysis for Wireless Powered Cooperative Networks

Future of massive Internet-of-Things (IoT) and low latency applications hinges on delivering fresh information time. Thus, to analyse data freshness for time critical use cases in future networks, the age (AoI) measure is introduced. Besides, energy harvesting also essential improve sustainability lifetime a power-constrained cost-efficient network. Therefore, we investigate new network architecture suitable IoT where connectivity, are emerged. We study wireless powered cooperative network, wherein source relay charge their finite-sized capacitors by from power station. For decode-and-forward (DF) amplify-and-forward relaying strategies, average AoI peak (PAoI) investigated indicate how randomness data/power transfer size affect metrics. It shown that, although utilizing power-limited imposes more delay, metrics could be improved. Specifically, DF scheme with waiting due signal processing, may achieve lower PAoI improving reliability. Furthermore, special proposed system discussed, e.g., full-power nodes one-shot successful transmission. Finally, numerical results provided clarify when strategy can outperform direct transmissions. that all values capacitors, position relay, station’s power, etc, there not unique optimal transmission minimize
