How to Quantify Packet Importance for Real-Time Control: A Feature-Oriented Perspective

Fueled by ubiquitous connectivity, packets are expected to be timely updated to the controller of interest in real-time control systems. Recently, the Age of Information (AoI) becomes a popular metric to quantify the packet importance, which improves the efficiency of communication resource utilization. However, it is analyzed only from the information freshness perspective, losing sight of consid...
