Özet

The concept of Age of Information (AoI) has emerged as a measure of data freshness in status-update-oriented applications. Enhancing AoI often involves unconventional networking strategies that adjust update transmission rates based on network conditions and resource variability. However, most prior research on AoI has been theoretical, assuming ideal network models and known delay/service time distributions. In real-world networks, obtaining these statistics and optimizing for them is challenging. In this study, we introduce Age-Aware Application Layer Forward Error Correction (A3L-FEC), a data flow controller at the application layer of the OSI model. A3L-FEC aims to enhance data freshness by preventing age violations, achieving this through reliable transmission of fresh data using forward error correction and the user datagram protocol.
