Age of information (AoI) and energy efficiency (EE), as two important performance metrics in
status update systems, usually cannot be simultaneously optimized. This paper investigates …

We consider the problem of minimizing the time average cost of sampling and transmitting
status updates by users over a wireless channel subject to average Age of Information …

This paper investigates bandwidth minimization under AoI constraints-a fundamental
problem that has not been studied in AoI research. The problem is of critical importance in …

In this work, we combine the two notions of timely delivery of information to study their
interplay; namely, deadline-constrained packet delivery due to latency constraints and …

The problem of scheduling packets from multiple sources over unreliable channels has
attracted much attention due to its great practicability in the Internet of things systems. Most …

Recently, has been recognized that there is a practical limitation with the original notion of
Age of Information (AoI) metric in terms of quantifying the freshness of information content. A …

The notion of age of information (AoI) has become an important performance metric in
network and control systems. Information freshness, represented by AoI, naturally arises in …

In many IoT applications, information needs to be gathered from multiple heterogeneous
sources to the base station for real-time processing and follow-up actions. Undoubtedly …

In multi-access edge computing (MEC) systems, there are multiple local cache servers
caching contents to satisfy the users' requests, instead of letting the users download via the …

Age-of-Information (AoI) is an application layer metric that has been widely adopted to
quantify the information freshness of each information source. However, few works address …
