The 1st International Workshop on the Age of Information
(AoI Workshop 2018)
Monday, 16 April, 2018 ● 08:00– 17:00 ● Room: Honolulu 3
The freshness of information is of fundamental importance in information-update and data analytics applications (e.g., crowdsourcing, financial trading, social networks, and online learning), as well as networked monitoring and control systems (e.g., sensor networks, airplane/vehicular control, robotics networks, Internet of Things, and Cyber-Physical Systems). The Age of Information is a new concept that can serve as a performance metric for characterizing the freshness of information, as a means for fundamental research, and as a tool in numerous applications. Recent research advances on the Age of Information suggest that many well-known design principles (e.g., for providing high throughput and low delay) that lead to the success of traditional data networks are inappropriate and need to be re-examined for enhancing information freshness in the rapidly emerging real-time applications.
The 1st Workshop on the Age of Information (AoI Workshop) will provide a forum where researchers and technical experts can share the latest research insights, and present key and emerging results on the Age of Information, and identify new challenges and opportunities.
