Age-of-Information Aware Scheduling

2018 International Conference on Signal Processing and Communications (SPCOM), 2018
We study the task of scheduling in a multi-source system where sources report their time-varying information to a central monitoring station via multiple orthogonal channels. The Age-of-Information of a source is defined as the amount of time elapsed since the latest update from that source was received at the monitoring station.

Age of Information of SIC-Aided Massive IoT Networks With Random Access

IEEE Internet of Things Journal, 2021
Age of Information (AoI) has turned to be an outright metric to evaluate information freshness in Internet of Things (IoT) networks. In this work, we evaluate the average AoI of an uplink IoT monitoring network where multiple end devices have independent

Guest Editorial Age of Information

IEEE Journal on Selected Areas in Communications, 2021
With the emergence of real-time cyberphysical systems, status updates are becoming an important form of communication. Vehicular messaging, security reports from homes and offices, surveillance video, and video feedback from remote-controlled systems all represent status updates at networked monitors that need to be as timely as possible. However, this

On the Age of Information With Packet Deadlines

IEEE Transactions on Information Theory, 2018
We study the age of information , which is a measure of the freshness of a continually updated piece of information as observed at a remote monitor. The age of information metric has been studied for a variety of different queueing systems, and in this paper, we introduce a packet deadline as a control mechanism to study its impact on the average age ...
