Call for Papers

The freshness of information is of fundamental importance in networked monitoring and cyber-physical systems such as sensor networks, airplane/vehicular control, robotic networks, and the Internet of Things, as well as in information-update and data analytics applications such as crowdsourcing, financial trading, social networks, and online learning. Age of Information (AoI) is a new concept that describes performance metrics for information freshness, as a means for fundamental research, and as a tool in latency-sensitive applications. Recent research advances on AoI suggest that many well-known design principles (e.g., for providing high throughput and low delay) of traditional data networks need to be re-examined for enhancing information freshness in emerging real-time applications.

This special issue is dedicated to communication theory, information theory, networking and signal processing aspects of networks and edge-cloud processing systems that enable latency-sensitive information-update systems. We solicit original papers in areas (not limited to):

• Age-optimized network protocols (e.g., transport, routing, and medium access)
• Age of information analysis and control in multiuser communication systems
• Timely updating in sensor networks
• Timely updating in networks of energy harvesting devices
• Data freshness in caches and databases
• Timeliness in cloud computing and storage
• Age of information and information theory
• Age-optimized source and channel coding
• Age of information and machine learning
• Age of information and control theory 
• Timeliness in signal tracking and estimation
• Age of information in security and privacy
• Age of information and game theory
• Economics and pricing of fresh data
• AoI as a performance metric for real-world cyber-physical systems (e.g. health and energy monitoring, real-time surveillance, networks of autonomous vehicles, augmented/virtual reality)
